Abstract

PURPOSE:To make it possible to execute the editing work of a curved part in a graphic pattern while matching the curved part with the other curved part by specifying points on the 1st and 2nd curves constituting the graphic pattern, generating a virtual line relating to the 1st and 2nd curves and changing the virtual line. CONSTITUTION:The coordinates of an optional point I1 e.g. in a CRT edition area is inputted by a pointing device(PD). Then, the coordinates of a point I2 e.g. are similarly inputted and the outline data (the coordinates of a sampling point) of a segment graphic Y1 are calculated based upon the coordinate values of the points I1, I2. The outline part Y1 is constituted of end points E1, E2 and intermediate points M1, M2 and the coordinates values of the these sampling points are calculated by equalities I. Provided that K is a constant stored in a program memory 6. Thus, the edition work of the curved part in the graphic pattern can be executed while matching the curved part with the other curved part.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a graphic processing method for graphic editing.

[Prior Art] In order to handle characters in electronic devices such as word processors, workstations, or printers, character sets (fonts) are usually used in units of fonts.
is required, and therefore a large amount of character data must be prepared. Particularly in the case of Japanese fonts, each font requires at least about 6,500 characters as specified in the ``JISXO208r Kanji Code System for Information Exchange''. Furthermore, unlike the bitmap method, the method of expressing characters using outline data has the advantage that it is possible to output characters of any size using a single type of character. In some cases, a design that is even more demanding than the analog original type is required.

The creation of photos based on these factors is largely manual work, and the work time required for each character can range from tens of minutes to even several hours, making it extremely inefficient.

In addition to the above fonts, when editing characters, figures, etc.,
Basically, the following functions can be considered.

First, there is digitization, a function that optically scans the basic analog character pattern to create binary digital data and generate character outline data.

Next, there is a function to create final outline data with the desired quality by editing the editing outline data generated and created by character production, that is, digitization.

However, in the graphic processing described above, there were the following points of inquiry.

Conventionally, editing work for curved portions of graphic patterns can be performed for each curved portion, but there has been a problem in that matching with other curved portions has not been considered.

[Objective] In view of the above points, an object of the present invention is to provide a graphic processing method that allows editing of a curved portion of a graphic pattern while maintaining consistency with other curved portions.

[Explanation of Terminology] Here, the terms, operations, etc. necessary for explaining the present invention will be explained below.

The original data is the contour of the image data read by IR7 expressed by 8 adjacent data. From now on, the original data will be referred to as the original, and the file that stores the original data will be referred to as the original data file. The original data file is created on DISK 3 in FIG.

Next, font data will be explained using FIG. 9.

Al and a2 displayed as solid lines are called contour lines.

For example, the contour line is composed of a cubic B-spline curve, a straight line, and a combination thereof.

The circles shown at a3 in FIG. 9 are the control points of the curve excluding the start and end points of the curve, and are called intermediate points. The squares in A4 indicate the starting and ending points of a curved line or the starting and ending points of a straight line,
These are called end points. The end points and intermediate points are collectively called sample points. The terms "end point" and "intermediate point" sometimes refer to the point itself, and sometimes refer to the characteristic of the point.

The file that stores this font data is called a font data file. The font data file is created on DISK 3 in FIG.

When handling the above-mentioned font data, an absolute coordinate system and a design coordinate system as shown in FIG. 11 are applied as appropriate.

These differ in the direction of the y-axis, but the absolute coordinate system is suitable for handling data, and the design coordinate system is suitable for creators to design characters.

Next, the operation in this embodiment will be explained.

The operation is performed by moving the PD12 in FIG. 1 or pressing a button. The PD 12 in this embodiment has three buttons. From left to right, they are called the left button, middle button, and right button, respectively. Basic button operations on the PD include the following: pressing the button, releasing the button, moving the PD while holding the button, and moving the PD while releasing the button.

In the operation description of this embodiment, the following terms are used in combination with the above-mentioned operations.

A series of operations in which you press a click button, do not move, and then release the button.

Double Click Clicking twice within a certain period of time. Similarly, you may click three or four times.

drag Move the PD while holding down the button.

Release Release the button you were pressing. The above-mentioned drag is terminated by release.

Move the FD to the position of the item to be selected and press the button. Buttons are not limited.

Menu selection Picking the menu to be selected, for example with the left button.

und.

Undo refers to returning changes to figures, etc. caused by the previous operation to their previous state. For example, the fourth aspect of the present invention
In FIG. 89, there are the following steps: 1. Cancel the selected point 2. Cancel the position clicked by the PD 12 3. Return the changed graphic data to the data before the change and return the display to the previous state.

red.

Redo means to return the data and display of figures, etc. that have been undone to the state after the change (und).

undo).

[Symbol Definitions] Next, symbols used when explaining the present invention are defined below.

As mentioned above, the end point is expressed as Ei, the intermediate point as Mil, and the end point and the intermediate point are collectively expressed as Pi.

Let the contour line be expressed as Li.

Let the input data be expressed as Ni.

Let the position input be expressed as Ii.

[Contour Data Storage Unit] FIG. 10 shows details of the outline data storage unit on the RAM of PMEMS. FIG. 10(a) is an area that holds the number of contour lines n1oop constituting a character pattern. 10th
FIG. 10(b) shows the arrangement of the area for holding the number of sample points npoint forming each contour line and the address addrl of the sample point information storage area of FIG. 10(d).

FIG. 10(d) is a diagram showing the arrangement of areas for storing sample point information. Sample point information is coordinate value X5y
s If the detailed fish debris property and sample point is the starting point of a curve, this is the area for storing the attributes of the curve, that is, the address of the array shown in FIG. 10(e). FIG. 10(e) shows the attributes of a curve, in this case, taking a cubic B-spline as an example, the number of sets of coefficients ncoef and the coefficient anSbn for determining the curve.

This is an area for storing c,,dゎ (n=o, 1...).

If the parameters indicating the curve attributes change, Fig. 10(e)
It goes without saying that the structure of the area that stores the attributes of the curve shown in FIG. Taking the rDJ pattern shown in Figure 1O (C) as an example, Figures 10 (a), (b), (d), and (e)
will be explained in detail. The character pattern in Figure 10(c) is composed of two outlines, LO and Ll, so (a)
The value stored in the area shown in, that is, n1! oop is 2
becomes. (b) is an array of size equal to the number of contour lines, so in this case, it is an array of size 2, and each 17 (L
O), 13 (LL).

In the sample point information storage area (cl), P [0]
is the end point and not the starting point of the curve, so PDATA[
0] has a point attribute value of O. P [1] has endpoints,
Since this is the starting point of the curve, the point attribute value of PDATA [1] is the number of curve configuration sample points, which is 4 in this case.

Furthermore, since P[1] is the starting point of the curve, it holds the address of the curve attribute storage area (e). PDATA [1
], the ncOef of the curve attribute storage area (e) holding the address becomes 1, and aOSbO1CO% d O is stored in the RAM.

Correction work such as point deletion, point movement, etc. performed by the operator using the PD 12 is realized by referring to/modifying FIGS. 10(a), (b), (d), and (e).

The display changes on the CRT 13 are shown in Figure 10 (a), (b), (
This is done by converting into bitmap data and transferring it to the VRAM 14 with reference to d), (e), etc.

[Create file] Next, file creation S1 in FIG. 2 will be explained.

FIG. 8 shows a file creation menu displayed on the CRT 13. From this file creation menu, by picking a new or changed item on the PD, the screen moves to the file creation screen shown in FIG. 12. In the case of changes, the currently entered contents will be displayed. Pick each item on the PD and enter it on the KBD. By picking the creation of Yl with PD,
A new file is created or the header section is changed.

By picking the end of Y2 with the PD, the process returns to FIG. 8 and the file creation ends.

Files include outline data files, original data files, radical data files, and element data files, all of which have the following structure. The structure of the file is shown in FIG.

The header section contains data to be managed for each file and information regarding the structure of this file. The index section has information regarding the code of each data and the storage address of the data. The free space management section manages the free space in the data section. The data section is an area for storing data for each figure, and is divided into blocks for use.

Digitizing Next, digitizing (S2) shown in FIG. 2 will be explained. Digitizing is a process of automatically creating original data files and font data files from original characters.

The above process includes the following steps as shown in the flowchart of FIG. That is, scanning, code setting, center setting, noise removal, and contour line generation.

The created original data file and font data file are stored in DISKa shown in FIG.

In digitizing, as shown in FIG. 8, by picking the font code of a-1 with the PD 12, the font code is selected and displayed on a-2. By picking the digitizer a-6, the screen moves to the digitizing initial screen shown in FIG. 14.

A font code is displayed in b-1. b-2 is a message area. b-3 is a digitize menu, and b-4 to b-6 are submenus. Each menu is on P.
It can be picked with D12.

Digitizing is done page by page. In the example of the present invention, 1
There are two types available: 1 page with 5 characters and 1 page with 9 characters, and it can handle up to 5 pages. The flowchart in FIG. 3 corresponds to the menu in b-3, and the next menu cannot be picked unless each page is in the order of this flow, that is, the previous step has not been completed.

For each user to manage the progress of digitization, m a n
ag efile is prepared. m a n
a g e fi I e is a matrix of number of pages x number of characters, and a completed step flag is set for each character on each page. For completed steps, the menu field will be reversed and turned black, making it impossible to pick. PD1
When you pick b-5 in step 2, the screen moves to Figure 15, and by picking an arbitrary page number and selecting YES, the flag of the managefile of that page is initialized,
You can cancel digitizing the page.

Digitizing is completed by picking b-6 with the PD 12, and when digitizing is started again, it starts from the step continued from the previous step. When the digitization of one page from scanning to outline generation is completed, the m a of that page is completed.
The flag of n a g e fi 1 e is initialized, and all the menu fields of that page of b-3 are reversed and become white (and can be picked).

The resolution of the IR7 can be set in the environment variable of the CPU 15, and by referring to this at the time of scanning, any resolution can be supported.

In addition, by marking the center mark indicating the position of the document and the scan direction on the document mount in advance, it is possible to read this at the time of scanning, automatically recognize the distortion of the document and the scan direction, and perform appropriate processing. . 16th
An example of a manuscript is shown in the figure.

Further, in a menu column where it is necessary to recognize which image data it is, such as the scan column in FIG. 19, for example, a reduced version of the image data read by the IR 7 is displayed.

・Scan The scan procedure will be explained using the flowchart shown in FIG. Select a menu with PD12, and if it is b-9, end (step). I if it is scan 1-5
R7 is activated, and the image data of each character for one page of the original is stored from PMEM 6 to DISK 3 in a preset order (step 2).

Next, as shown in FIG. 17, 15 characters are displayed in a reduced size on the CRT 13, and one character located in the center of the document is displayed in a larger size (step 3). A center mark is written on each character of the manuscript, making it possible to detect rotation and distortion of the manuscript.

If necessary, rescanning can be performed by picking b-7 with the PD 12 (step 5). At this time, it is also possible to specify the characters to be rescanned using the PD 12 and perform partial rescanning. Furthermore, by picking b-8, scanning of that page can be canceled and the original data in DISK 3 is also deleted (step 6).

Finally, update managefile (5step 7),
finish.

・Code setting From Figure 14 b-3, select the menu of the appropriate page of code settings 1 to 5 with the PD12.
Moving on to Figure 9. However, in this case, the pickable page number
, the scan must have finished.

The code setting procedure will be explained using the flowchart of FIG. 20. First, variables are initialized (step).

By picking the code field of b-10, KBDl
Code input becomes possible from l (step 2). If the picked code field is at the code setting temperature (step 3), the number of set characters is reduced by 1 (step 4). Enter the code from KBDII (step 5), and once it is set (step 5).
p7) The character corresponding to the character code is displayed in the corresponding column of b-11 (step 8), and 1 is added to the set number of characters.

For example, if the code system is JIS and the code is 2344, "D" is displayed.

Also, by inputting -1, it is possible to ignore that character from now on and not generate an outline (step 6).
).

Also, by picking b-12 serial number processing, it is possible to perform serial number processing based on the code system (ste
plo).

If the codes of all characters are set and b-13 is picked with the PD 12 (step H), the manage file is updated and the process ends (step 2).

- From center setting b-3, move to FIG. 21 by picking an appropriate page menu of center settings 1 to 5 with the PD 12. However, in this case, the page number that can be picked is
Code setting must be completed.

The center setting procedure will be explained using the flowchart of FIG. 22. First, use the PD 12 to pick the scan field of the character for which center setting is to be performed (step).

This will display the picked image data (s
(step 2), the cursor of the PD 12 changes to a cross (step 3), and center setting becomes possible.

Place the cursor on the center mark marked in advance on the document mount and click the left button on the PD12 (
As a result of step 4), a body frame appears on the screen (step 5). After this, fine adjustment can be made by moving the center in units of one dot using the arrow keys of KBDII (step 8).

For the size of the body frame, set the pitch column of b-14 to PD12.
You can change it by picking it (step 6) and inputting it from KBDII (step 7). Further, this pitch information can also be automatically input from OCR or character code.

The center setting is automatically determined for each character by picking the next character, and when all character settings are complete, b-
If you pick the next menu from 3 or b-15 (step), the managefile is updated and the process ends (step).

- From Noise Removal b-3, move to FIG. 23 by picking an appropriate page menu of Noise Removal 1 to 5 with the PD 12. However, in this case, the center setting must be completed for the page number that can be picked.

The noise removal procedure will be explained using the flowchart of FIG. 25. First, the PD 12 picks the scan field of the character whose nozzle is to be removed (step 1). As a result, image data is displayed as shown in Fig. 24 (step
2). Here, noise refers to things other than the necessary image, such as blurring of the image that occurs when reading with a scanner, dust in the document, and registration marks.

Noise removal is performed by turning on or off bits of the corresponding image data stored on the PMEM 6. It should be noted that in the explanation here, it is assumed that in a necessary part of the image data, that is, a part representing a character, the corresponding bit in the memory is 1 (on).

The present invention introduces the concept of a body frame, and has functions such as extra-body deletion that turns off all bits outside the body frame, and functions that turn on or off the inside or outside of a specified rectangle.

The deletion outside the body is executed by picking b-15 with the PD 12 (step 3.4). If there is more noise (step 5), depending on the type of noise (step 6)
, b-16 menu with the PD 12, and switch on (step 8) and off (step 7) in the rectangle. Specify the range by dragging with PD125
step 9), noise removal is performed (step 1O).

By picking the next character, noise removal for that character ends (5tepH), and the image data is DISKa.
The previously picked scan field will be highlighted to indicate that the character is finished.

After noise removal of all characters is completed, pick b-17 with PD12 or pick the next menu from b-3 (st
epH) by m a n a g e f i
Ie is updated and the process ends (step 12).

Further, noise is automatically removed in the next contour line generation.

・Outline generation-3 starts automatically by picking a menu of appropriate pages 1 to 5 of outline generation on the PD 12 (FIG. 26). However, in this case, noise removal must be completed for the page number that can be picked.

The outline generation procedure will be explained using the flowchart of FIG. 29. b-4 parameter setting menu on PD12
When you pick (step), the automatic noise removal maximum value is displayed, as shown in FIG. 27, for example.

By default, it is set to 80, and this value is the number of dots that make up the contour, and as a result of contour tracking, contours smaller than this value are regarded as noise and are not regarded as a contour point sequence. For example, an isolated point consisting of 24 dots is considered noise. Note that this value can be input and changed from KBDII by picking b-18 (step
2). In addition, parameters for feature point extraction and sample point automatic generation when automatically generating font data can be changed. This makes it possible to control the optimal contour data generation method for each typeface, such as a typeface with many straight lines such as Gothic, and a typeface with many curved parts such as cursive. These parameters are stored in PMEM6, for example, depending on the typeface.

Extract a sequence of contour points from the image data from which noise removal has been completed and create original data (5step 3)
, stored in DISK3. This original data can be referenced on the CRT 13 at any time during character production.

Generally, image data such as characters is composed of a plurality of contour lines, but in this case, all point sequences indicating the "inner edges" of the image data are extracted.

The point sequence data extracted in this way becomes a set of coordinate values (xi, yi) from the reference point of the image data.

The method of extracting the contour point sequence is realized by using a method proposed by the applicant in Japanese Patent Laid-Open No. 64-71767, etc., or a generally known contour tracking method.

Furthermore, feature points are extracted from the original data obtained here, straight parts and curved parts are determined, and font data representing characters is automatically generated (Fig. 29, 5 step 4).
. Here, the feature points refer to the end point (E4) of the contour point sequence, the maximum/minimum point (E2), and both end points (El, E3) of the straight line portion, as shown by squares in FIG.

After extracting feature points, for the point sequence section determined to be a curved section, for example the section from El to E2, spline fitting processing is performed to automatically generate sample points M1 and M2 necessary to express the corresponding section. do.

After applying this spline fitting to the entire curve section and creating font data constituting one character in memory, DIS
Store it in the font data file created in K3.

When contour line generation is completed for all characters (step 5), the managefile is automatically initialized and finished (step
6).

[Character Production] Character production is performed by performing various operations on the basic screen shown in FIG. 30. Although the explanation is given here in letters, it goes without saying that the explanation is not limited to letters. In the example, the basic screen has 1280x1024 pixels and consists of the following contents. FIG. 30 will be explained below. A-1 is a character display area, which is composed of an editing area (A-11) for displaying and editing a character pattern being edited, and a compositing area (A-1-2) for displaying a compositing pattern.

A-2 is a code area, and the left part is a font code indicating the file name containing the character pattern being edited. The right part is the character code of the character pattern being edited.

A-3 is a coordinate value area. The “real-time” value indicates the coordinate value of the point currently under control in x and y.
Numbers 1 to 4 above indicate the coordinate values X and y of the latest four points as well as the differences dx and dy between the coordinate values of the previous and subsequent points. 4～
Each time a new point is controlled in the order of 1, it is scrolled upward.

A-4 is a message area that displays error messages and the like for various operations.

A-5 is a menu area for character creation, which is divided into five areas, FIG. 30(b) to FIG. 30(f).

Each menu process is basically terminated by picking another menu. Furthermore, the execution order and number of executions of all menus are not limited.

FIG. 30(b) is a menu area related to screen display changes such as scrolling and redisplaying the character pattern being edited.

These menus are controlled by an interrupt menu control method, which will be described later, which is different from the normal menu control method.

The display controls are not exclusive (eg, a combination of zooming and scrolling, etc.) is also possible.

FIG. 30(c) is a menu area related to character data modification such as transformation, composition, and point control.

FIG. 30(d) is a menu area where character information such as point coordinates is displayed.

FIG. 30(e) is a menu area where character information such as pitch, line settings, etc. are performed.

FIG. 30(f) is a menu area related to character data storage such as return, -time storage, and registration/termination.

A-6 is a composite pattern control menu area, which is divided into two parts, FIG. 30(g) and FIG. 30(h).

FIG. 30(g) is a menu area used for changing the screen display such as scrolling the composite pattern, and FIG. 30(b)
) is an interrupt menu similar to the editing display control menu.

FIG. 30(h) is a composite pattern call menu.

The character correction work begins by calling character data to the editing area A-1-1 in FIG. 30(a).

Character data is loaded from the character data storage area on the DISK in FIG. 1 to the PMEM in FIG. 1 through the I10 interface in FIG. 1 and 2.

In the PMEM of 6, the data is processed for display and shown in Fig. 1.
Transfer the display data to the VRAM of 4, and
Display on RT.

When modifying characters after calling character data, rules are set for the positional relationship between end points and midpoints in order to standardize the design and add line width information to prevent deterioration of display quality at specific sizes.

The rules are that the end points must be taken at the maximum or minimum points on the continuous curve of the contour, and the intermediate points must be on the horizontal or vertical line passing through the end points.

The functions of moving the point 59-d and aligning the point 59-e in FIG. 4 are based on this convention.

Among the menus in character data correction S9 in Figure 4, for those that require sample points to be displayed, if the sample points are not displayed when selecting the menu in S9, the sample points will be displayed automatically. I have to.

After calling the character data, correction work is performed by operating the PD 12 and keyboard 11. This operation will be explained using FIG.

PD operations such as menu selection and sample point selection are as described above (terminology explanation).

For precise input such as moving sample points in units of several dots, please refer to KB.
Operate the arrow keys on the DII.

In this case, the PD 12 has three buttons, which are used as appropriate in each menu.

When you operate the PD, arrow keys, etc., the information is transferred to PMEM.
In PMEM6, DIS
It inputs data from K3, changes and processes data already on PMEM6, transfers the data to VRAM14, and displays it on CRT13.

undO11red.

Next, the aforementioned undo-redo will be explained.

In the present invention, the timing for instructing the execution of undo-redo is, for example, when the right button of the PD 12 is clicked in the operation role of each menu process.
Und is used as input for executing do/redo operations, and is to be performed in each processing procedure.

and redo (undo of undo), or provide a menu for undo-redo, which will be described later, and when the menu is selected, undo-redO is executed for the last change in graphic data.

FIG. 31 shows undo/red by changing graphic data.

10 is a flowchart showing an example of implementation, the figure data table is a table storing the figure data in FIG. 10, and the number i of each figure is represented by Fi,
The undo table has the same table format as the figure data table, and is a table that stores the figure number and data only for the figure Fi in the specified figure data table. This is a table that allows data of the same number to be exchanged regarding Fi. In the flow diagram, 5tepl is undo
This is a step that instructs to return to the state before the change when the execution is instructed. This instruction is determined according to the processing of each menu, and when this instruction is received, the contents of the undo table are cleared ( step 2). Next, the operator inputs the next data N, and in 5step 4, if that N is an operation that instructs to change the figure data Fi, such as deleting one vertex of figure Fi, in 5tep7, figure F1 is not stored in the undo table, the Fi
, store the data of Fi in the figure data table as the data before the change in the undo table together with the figure number (5step 8), change the data of the figure data table Fi in 5step 9, and display the result.
plo), and waits for input of the next data N (step 3).

If Fi is already saved in the undo table at 5step7, skip 5step8 and proceed to 5step9.
Proceed to. That is, in 5tep7, the process proceeds to 5tep8 only when there is a change instruction for the first time after clearing the undo table regarding the figure Fi.

Next, in 5step 4, when input N is an undo instruction (step 5), all data Fi in the undo table is exchanged with Fi in the figure data table (5tepH), and the result is processed in the same way as in 5teplO. , performs display processing (step 12), and then inputs the next data (step 3). If an end instruction is given in step 5 (step 6), this menu processing is ended, and if there is any other instruction, other processing is executed in step 13, and the process returns to step 3.

Also, when there is an undo instruction again in 5tep5, in the process of 5tepH, all figures Fi in the undo table will be exchanged again, so redo will be performed, and in 5tep11-12,
This means repeating undo/redo.

Interrupt Menu Control Interrupt menu control will be explained. An interrupt menu is a menu that can be executed during normal character data correction menu processing without interrupting the operation.

FIG. 32 is a diagram explaining the interrupt menu control method for executing the interrupt menu, and FIG.
32(a) is a diagram briefly explaining the internal flow of normal character data correction menu processing, and FIG. 32(b) is a diagram illustrating the input control section in FIG. 32(a).

The input control unit accepts input from the PD 12 and KBDII, and outputs input information from the operator, such as whether it is a menu pick or a sample point pick.

The flow of processing in the character data correction menu will be explained using figure (a).

Here, it is assumed that whether or not the type of menu is an interrupt menu is determined in advance by having a flag or the like in the menu.

Receives input from the operator at 5 tepl (N1)
, If N1 is another menu, end the menu processing, and if it is not another menu, perform processing according to the contents of each menu (step 3), wait for input from the operator again (step 1), and repeat this process. performs menu processing. This makes it possible to exit each menu without issuing an exit instruction.

The input control section will be explained in (b). Receive the input information from the operator in 5 tepl, set it to N1, and repeat it in 5 tepl.
2 determines Nl, and if N1 is not an interrupt menu, outputs N1 and ends the process. When N1 is an interrupt menu, each interrupt menu process is performed here in step 3, the next input is waited for (step 1), and the input control section is not terminated. That is, when the interrupt menu is instructed by the operator, it is processed within the input control section, and each step in (a) is not interrupted.

[Display Control] FIG. 33 is a diagram simply showing the flow of display control in character production S3, where 33-1 is the part with each function of character data correction of N9 in FIG. The part having each function of display control of N8 in FIG. 4, 33-
3 is a part for changing font data, 33-4 is a part for changing display data, and 33-1 to 33-
4 is on PMEM6, and 33-a is on 33
- If the font data actually changes in 1,
It means to request 33-3 to change the font data, and similarly, 33-b also requests 33-2 to change the display data, etc.
33-C indicates a request to 33-4 to change the display due to the font data change, and 33-d indicates that the actual 1mCRT131mV is changed from 33-4.
This means that a display request is made through the RAM 14.

To explain the flow a little more, if font data is changed during character data correction work in 33-1, 33-1
-3 issues a data change request 33-a, and after actually changing the font data in 33-3, issues a display change request 33-c to 33-4. At 33-4, the font data is referred to, display data is created, and a display request is sent to the CRT (33-d) for display. If there are display change requests from two display control units (33-b), only the display data is changed at 33-4 and displayed on the CRT.

Each function of 33-2 is the above-mentioned interrupt menu, so even if 33-4 receives a request from 33-2 to 33-b while modifying character data, requests 33-a or 33-3
It will not affect the processing.

33-4 will be explained using FIGS. 33 and 34.

FIG. 34 divides the processing contents in step 4 into two parts, (a) showing the flow of display data creation processing, and (b) showing the flow of display data display processing. In (a), font data, original data, line data, and these data are set as one set, and the number assigned to that data is, display magnification rate S1 display reference point coordinates 0, and when dividing a curved part of font data into a straight line. The curve division interval N, which is a parameter serving as a guideline, is input, and the font display data, original display data, and line display data developed in the display coordinate system are output in correspondence with the display data number No. Therefore, by changing the value of No., it is possible to have multiple sets of output data.

(b) shows the font display data, original display data, and line display data that are output from (a), as well as their data number No., a flag DT for selecting data in the set, and the selected data. A flag ST that indicates the display format of the data, a flag PF that determines whether or not to display the data in a filled manner, and a WD that indicates the display destination of the data.
PL to indicate the plane.

Inputs a flag DS that instructs whether to actually display or erase,
Expand bitmap data to VMEM.

Each step will be explained in turn.

Input S, which is the enlargement rate or zoom rate at the time of display, at 5 tepl. 5. In step 2, input the coordinates ○ that will be the display reference after zooming. The SSO parameters are generally the same as the parameters required when performing coordinate transformation from an absolute coordinate system to a display coordinate system. Curve division interval N at 5tep3
Enter. In step 4, the font data already on PMEMA is coordinate-transformed using SSO, and sample point display data shown in FIG. 35 (c) is created from the sample point data of the font data shown in FIG. 10 (d).

In step 5, the sample point display data created in step 4, the coefficients in FIG. 1O(e), and the curved portion of N are developed into short vectors. Needless to say, the number of divisions can be changed depending on the value of N. The data expanded into short vectors is converted into PME as short vector data.
Hold on M (d).

Here, FIG. 35 will be explained. (a), (b)
The explanation is the same as (a) and Cb') in FIG. In addition, DDATA in (c) is the coordinate po(x) of the sample point in FIG.
x), Pn-1(y) are coordinate-converted values for display, and regarding point attributes, L is the line start point,
C means the starting point of the curve, and when it is C, it indicates the address of the area (d) where the curve part is expanded into a short vector ((d) is the number of point coordinates npt and the npt coordinate values It is stored.

In step 5, the original data on the PMEM is also subjected to coordinate transformation in the same manner as in step 4, and is stored on the PMEM as original display data. The same applies to the line data of 5tep7.

Next, (b) will be explained.

In step 5, a flag number No. which determines which data set to use among the font display data, original display data, and line display data created in (a) is input. In step 9, a flag DT for determining which data to display among the numbers is input. DT=1
When , font display data is input, when DT=2, original display data is input, and when DT=3, line display data is input.

In step 5, the display format ST is input. ST is D
Valid only when T=1, takes three values, 5T=1 (7
) time is DDATA(7) curve display, 5T=2(7) time 1
;! Linear display of DDATA, DDATA when 5T=3
The sample points are displayed as follows. In other words, when displaying a curve, (
In c), when the point attribute is C, refer to addr2,
The data including the short vector data in (d) and sequentially connected by line segments is used as display data. When displaying a straight line, (C
) and only the data of sample point coordinates are connected in order as display data.

When displaying a sample point, data such as an end point being a square and an intermediate point being a circle is used as display data according to point attributes.

Figure 36 shows (a) curve display, (b) straight line display, (c)
FIG. 3 is a diagram showing an example of sample point display.

In 5tepH, input a flag PF indicating whether or not to fill in the outline of the display data selected in 5step 8.9 and the display data created in 5teplO. PF = 0 is an instruction to display the outline, and PF = 1 is an instruction to fill it. . At this time, when the data is line display data, this flag is not referenced.

At step 512, an area for displaying the display data created up to step 511 is input. WD is window
It doesn't matter if it is.

In 5tep13, if the VRAM can have a plurality of brains, a PL indicating the display destination brain is input. When there is only one brain, the flag is ignored.

In 5tep14, a flag DS is input which instructs whether to display or erase when expanding on the VRAM.

In step 14, the display data selected by DT is
T, DF, WD, PLSDSl: m following V RAM
14 into a bitmap and finish. After this step is completed, the image is displayed on the CRT from the VRAM.

Also, the data number No. specified through (a) and (b)
, can be considered to have one for each display destination area WD.

It goes without saying that various display combinations can be made by combining DTSST and PF.

Next, each function of display control will be explained. In FIG. 4, all display controls (S8-a-38-j) are interrupt menus, and as mentioned above, even if these functions are executed during character data modification, the operation during character modification is not interrupted. .

The scrolling of the scroll 58-a will be explained. FIG. 37 is a flowchart showing the scrolling procedure. First, 5 steps
Initialize it to 1 with l. 5. In step 2, input the display destination area WD'. W for scrolling the editing area
D' Edit area. 5 step 3 and PD the reference point 0'
Input from ll. In step 4, each person inputs No., DT, ST, and %PFSWD for display processing.

Set PL and DS. It is assumed that one No. exists for each designated WD, and F is a function that associates a WD with No. Here you can select the type of display data currently displayed.
data type DT (No,) i (i=o, n-1)
DT, and shall be stored on PMEM.
For ST and PFSPi, substitute their current values and set WD
is substituted with WD' in 5tep2, erase is substituted in the display flag DS, and the display is erased by the above-mentioned display processing in 5tep5.

5tep6 is 5tep for all data types (n)
This is the part that determines whether to repeat p4.5. If there is still data in the display state, i is incremented in step 5 and step 4.5 is repeated again.

Next, each step of displaying after scrolling will be explained.

In step 8, for the display data number No., the scale S and reference point O1 curve division interval N required for display data creation are input. The reference point O is O' input in 5tep3.
For SSN, the current value for display data number No. is substituted.

In step 9, create display data according to the display data creation procedure described above, set i=0 in step 5, and
In tepH, input values necessary for display processing are set. DT
, 5TSPF, and PL, the current display state corresponding to No. is substituted, and WD' and DS, which were input in 5tep2, are substituted with the display state, respectively.

In step 12, display is performed according to the display process described above,
In step 13, the current display state is newly stored in the PMEM, and this process is repeated for the amount of data to be displayed, and the process ends.

FIG. 39 is an example of FIG. 38 scrolled. In this case, WD' is a number associated with the editing area number F (WD'), the display data type is font data, so n=1, and no filling is specified for PF.

zoom Explain about zoom.

In the zoom process, simply add S as described in the scroll process above as a new operator input.
The subsequent processing is the same. That is, following 5tep3, the step of inputting the scale value S' is added, and 5tep8
The only thing that is substituted into S is S'. Therefore, only the WD' input, 0' input, and S' input section will be newly explained, and the rest will be omitted.

This will be explained using FIG. 40.

At step 5, the display destination WD' is input. If zooming is within the editing area, the editing area is assigned to WD'.

In step 2, change the cursor shape from long cross to red crane. The cursor will be explained later in step 3.
to display the display center. 5 Step 4 waits for input from the operator. If input Nd is other menu big, 5t
End processing is performed in ep17 and the program ends. The termination process includes processes such as returning the cursor shape to its original shape and hiding the center. When the first rectangle P1 is input in 5tep6, the input of the next rectangle point P2 is waited for in 5tep8. 5t
In ep9, if the input Nd is another menu, the process ends after the end process, and if it is an undo instruction (steplo), Pl is canceled (5stepH) and the process returns to 5step4. 5step1
When the rectangle 2nd fish P2 is specified in 2, for example, Pl, P
The length and width of the rectangle with 2 as the two diagonal points, w, WD
When the vertical and horizontal lengths of the area specified by ' are H and W, the magnification rate S' = min (H/ h,
/w) Center O''== center of rectangle.

In 5tep14, WD', S', and 0' are new inputs, the above-mentioned display processing is performed, and the process ends.

For example, when entering the magnification rate in step 5, the reference point is 0'.
is the current value, and display processing is performed in the same manner in step 516.

Regarding the input of Nd in step 5, step 6, and step 7, for example, if the left button is clicked, the PI is input, and if the middle button is clicked, the enlargement rate is input. Regarding the magnification rate in step 5, for example, when clicking above the center in the display destination area, the click is enlarged, and when clicked below, the magnification rate is determined based on the distance from the center.

Figure 41 shows the zoom processing screen, 41-1
is the display center, 41-2 is the long crosshair cursor, 4
1-3 shows the appearance of a rectangular echo, and FIG. 42 is a diagram zoomed in accordance with instructions from Pl and P2.

Needless to say, you can zoom the composite screen by changing the WD.

1 piece of work Explain standard sizes.

Standard size is a function that returns the scrolled and zoomed display state to the original size and display position in one go. The original display state means, for example, that 1 dat of font data corresponds to 1 pixel of the display area, and the display is performed so that the center of the body is located at the center of the display area.

In the display processing section described above, the initial scale S is input to S. This can be realized by inputting an initial reference point of 0° to SO and a new input of area WD'.

1st signal 0N-OFF The original ON-OFF will be explained.

This menu is a toggle menu, and each time you pick the menu, you can turn the original display on or off.
I do things.

This is also No-F (WD') in the display processing section (b).
This can be achieved by specifying WD' as the display destination area, DT←2, and setting and inputting DS←non-display if the original is currently being displayed, and DS-display if the original is currently being displayed. It goes without saying that by changing the PL when displaying the original display data, it can be displayed in a different brain from the font display data and can be viewed overlappingly.

Sample ON/OFF Sample point ON/OFF will be explained.

This menu is also a toggle menu. Display processing section (b
), NO←F (WD'), DT←1, ST←
Just enter 3.

FIG. 43 is an example showing the sample point ON and original ON states.

・ Zishiko's menu is also a toggle menu. Similarly No-F
(WD'), PF 4-ON, and display processing is performed by switching DS←display/erase every time the menu is turned on.

Here too, overlapping display is possible by changing the value of PL to the plane of the font display data.

FIG. 44 is a diagram with fill-in turned ON.

-In ON/OFF lines, for example auxiliary lines, will be described later. Here, regarding the line set while displayed in the line setting menu,
This is a function that can be displayed or hidden by clicking this menu. This menu is also a toggle menu.

Similarly, in the display processing section (b), No. 4 is used for the display method.
Input -F(WD'), DT←3.

FIG. 45 is a diagram showing the line ON state.

Cursor ON/OFF The cursors to be switched here are the long crosshair cursor shown in (a) of Figure 46 and the short hair cursor shown in (b). When ON, the long crosshair cursor is displayed, and when OFF, the short crosshair cursor is displayed. indicate. This display can be controlled, for example, by changing the cursor, or by having cursor data as display data and using the same processing method as display processing (b), as shown in the display control above. This can be achieved by displaying methods.

4 topsoil FIG. 4 32-10 Re-display will be explained.

Redisplay is a function that refreshes the display screen and displays it again when, for example, noise appears on the display screen or lines disappear due to some external influence.

FIG. 47 is a diagram for explaining the redisplay operation, and in each input waiting state (step) during character creation, when instructions are given by PD12 and KBDII (step
ep2), if it is a pick in the redisplay menu (step
3) Perform the redisplay process (step 5), return to the original input holding state (step 2), and continue the current character creation process if it is not the pick of the redisplay menu at step 3 (
step 4). Therefore, this interrupt menu does not interrupt the operation even in the middle of creating each character.

When redisplaying S5, the font data, menu data, message data, and echo data were referred to regarding the character data in PMEM6, and the data was processed for display based on the current display state and expanded on the VRAM14. After that, it is displayed on the CRT 13.

The method of re-displaying the font data is realized by erasing all the display data once in the display process shown in FIG. 34(b) and displaying it again in the same display state.

Regarding the insertion of point 11 and point 59-a in Figure 4, Figures 48 and 4
This will be explained using FIG.

The Insert Point function is invoked by picking the "Insert Point" menu.

Point insertion is a function that inserts and moves one or two sample points between two adjacent points to change a line segment or curve.

Figure 48 shows the state before point insertion, and if Ml and M2 are designated as two adjacent points, the interval E ) M 1M 2
E2 is the result of sample point insertion, the interval E in Figure 49
, M , M 3M 2 E 2.

In this embodiment, as a preferable example, the position of the insertion point is set at the midpoint of two adjacent points, and the point attribute of the sample point to be inserted is determined according to the following rules. That is, section D in Figure 48
2, when two adjacent points are end points, the specified section is a line segment, so the point attribute of the insertion point is set as the end point, and the section D in Figure 48
If one or both of the two adjacent points are the midpoint, as in 1, the specified section is a curve, so the point attribute of the insertion point is set as the midpoint.

Apart from this, there is a function to insert two intermediate points between two adjacent end points in order to change a line segment section to a curve section with a simple operation. In this case, the position of the insertion point is the adjacent 2
Use the internal division point of the end point.

The procedure for point insertion will be explained using the flowchart shown in FIG.

At 5 tepl, set the flag "insert FLAG" to indicate whether or not the point has been inserted.
Initialize J to OFF. In step 5, one point in the CRT editing area is selected with the left button of the PD 12, and it is designated as Pl. In 5tep3, the adjacent point P2 of Pl is 5te
Select in the same way as p2. In step 5, the point attribute of the insertion point is determined from the point attributes of Pl and P2 according to the above-mentioned fish waste determination rule. After recalculating the curve parameters of the section affected by point insertion and displaying them on the CRT 13 through the VRAM 14, the insertion FLAG is turned ON in step 5. 5
At step 6, the next input is accepted, and at steps 5, 7 to 10, the accepted input is determined. As a result of the determination, if the input is a menu pick, this function is terminated. In addition, if it is a normal point input, the input is made the first point input at 5 teph, and the processing from 5 tep 3 onward is repeated. Also, move instructions (arrow keys on KBDII)
If so, in 5tep12 the point inserted in 5tep is moved, the changed outline is displayed on the CRT 13 via the VRAM 14, and the process returns to 5tep6. In addition, 5tep
If the input in step 6 is undo (right button on PD12), determine the insertion FLAG in step 13,
If it is ON, in step 5 step 4 the inserted sample point is returned to the outline display before the sample point was inserted (the inserted sample point is deleted and the outline is redisplayed), and in step 5 step 17 the insertion flag is turned OFF. In addition, if the judgment in 5tep13 is OFF, in 5tep14, the state of the contour line after point insertion is reinserted, and the contour line is redisplayed), 5t
Turn on the insertion flag in ep15.

Through the steps 5tep14.15 and 5tep16.17, it becomes possible to delete or reinsert the previously inserted point and redisplay the contour line simply by operating the right button on the PD 12.

As mentioned above, in order to realize the function of changing a line segment section to a curve section (inserting 2 intermediate points), input the points in step 2.3,
12 middle button, and after inserting two intermediate points in step 4, transfer the outline (or section) to the CRT1 through the VRAM14.
Display on 3.

Next, the point deletion 59-b will be explained below using FIG. 112. To delete points, press the "Delete points" menu.
It is activated by picking at D12.

Point deletion is a function that deletes an arbitrary sample point or a plurality of sample points in an arbitrary range on the contour line, and re-interpolates and displays the curve. FIG. 113 is an example in which sample point P1 in FIG. 112 is deleted, and FIG. 114 is an example in which sample point P1 in FIG.
This is an example in which sample points included in section K in FIG. 12 are deleted.

The procedure for point deletion is shown in the flowchart in Fig. 115 and in Fig. 11.
This will be explained using FIG. 2, FIG. 113, and FIG. 114.

Initialize "Deletion FLAGJ", which is a flag indicating whether the sample point was deleted at 5tepl, to OFF.5t
Input the first point from PD12 in ep2. 5step3
Then, determine whether the input to PD12 at 5tep2 was a section instruction (pressing the middle button), and if it is a section instruction, consider point P to be the end point of the section as 1, and enter 5tep4゜5tep.
In step 5, enter 2 as the end point of the section and the point P2 on the section from the PD12. In step 5, sample points to be deleted from Kl and P2 are determined. If the input to PD12 at step 2 is not a section instruction, it is a one point deletion instruction and s't
In ep20, P input in step 5 is set as the sample point to be deleted. 5tep7, 5tep6 or 5te
The sample points determined in step 20 are deleted from FIG.

At 5tep9, accept the following input, and from 5teplo~
In step 12, the receiver determines the input. As a result of the determination, if the input is a menu pick, this function is terminated. Also, in the case of normal point power, 5 step 13
Then, with this input as the first input, the deletion FLAG is turned OFF in 5tep14, and the process from 5tep3 onward is repeated. In addition, the input at 5tep9 is undo (PD1
2 right button), (determination 5 step 12)
, the deletion FLAG is determined in step 15, and it is O
If N, the state before sample point deletion is displayed on the CRT 13 through the VRAM 14 in 5step 16, and
Turn off the deletion FLAG on p17. Also 5tep1
If the judgment in step 5 is OFF, in step 5 step 18 the state after sample point deletion is sent to the CRT 13 through the VRAM 14.
, and turn on the deletion FLAG in step 19. The sample points once deleted in steps 16.17 and 18.19 above can be restored and deleted again simply by operating the right button on the PD 12. (For example, the display of FIG. 112 and FIG. 113 can be switched by simply operating the right button.

) Next, the point deletion 59-b will be explained using FIG. 51 below. This function is read by picking the "Delete F point" menu using the PD12.At this time, if all sample points are not displayed on the character outline on the CRTla before picking the menu, by picking the menu. All sample points on the character outline are displayed.

Point deletion is a function to modify a line segment by deleting a specified point or multiple points within a specified area. To delete one point, pick the desired point with the left button of the PD12. To delete multiple points within a specified section, pick two points one point outside each end of the section to be deleted. This is executed by picking arbitrary points within the section to be deleted, a total of three points, with the middle button of the PD 12. FIG. 51 is a diagram showing an actual example of point deletion, and the alphabet in parentheses and the alphabet with a dash in parentheses indicate before and after execution in each case. That is, if both sides of the point to be deleted are straight lines (A), the point is interpolated into a straight line by performing the point deletion (A'). (B), (E) If one or both sides of the point to be deleted is a curve, by deleting the point, a new curve is interpolated.

(B') (E') If the point to be deleted is an intermediate point (
C), by performing point deletion, a new curve is interpolated at the remaining intermediate points (G'). However, if the midpoint of a curve with one midpoint is deleted (D), it will be interpolated with a straight line (D
').

Next, when deleting within the specified section, if the first two points picked are endpoints (F), E51 and E55.3 After picking the third fish E54, interpolation is performed in a straight line (F'). Furthermore, if one or both of the two initially picked points are intermediate points, after picking M62, M66.3 fish E63 in (G), interpolation is performed using a curve (G').

The blinking reversal 59-c in FIG. 4 will be explained below using FIGS. 52 and 53. This function is called by selecting the "flashing reversal" menu.

Blinking reversal is a function that inverts the attributes of the selected sample points, that is, changes the attributes of the selected sample points to midpoints if they are endpoints, or to endpoints if they are midpoints, and corrects the outline.

The procedure for blinking reversal is shown in the flowchart in Figure 54 and in Figure 5.
This will be explained using the editing screens shown in FIGS. 2 and 53.

At 5 tepl, select one point in the CRT editing area, for example, Pl.
Pick (M2). 5tep2, referring to the fish debris shown in FIG. 10(b) retained in PMEM6,
The end points and intermediate points are inverted, and the parameter table showing the curve in FIG. 10(d) is changed. Figure 10(a),
The data in (b) and (d) are processed for display and stored in VRAM1.
4, the modified outline is displayed on the CRT 13.

In the case of Fig. 52, M2 is changed to the end point, and E 1, M
l, M2, and E2 are El, Ml, and Ml shown in FIG.
It becomes E3, E2.

In step 3, accept the next input and press s t e p
In steps 4 to 6, the receiver determines the input. As a result of the determination, if the input is a menu pick, this function is terminated. In addition, if it is a normal point input, set the input as Pl in 5tep7 and repeat 5tep.
Repeat the process from 2 onwards. Also, the input of 5tep3 is u
nd.

(right button on PD12), set Pl to 5t
By inverting the point attributes again with epl, the current 1
You can return to the previous state. In this case, the state shown in FIG. 53 returns to FIG. 51.

Standing 1 Next, the point movement 59-d will be explained below using FIGS. 55, 56, and 57. To call this function, select the "Point movement" or "Black stripe horizontal movement" menu from PD1.
This is done by picking with 2.

Point movement is basically a function that moves one selected sample point to an arbitrary position, or only in the X-axis direction or only in the Y-axis direction, and at the same time corrects and displays the line segment. There are three ways to move selected points: That is, (1) when picking a point using the PD 12 described above, do not release the button after picking, just drag the PD 12 and release it at an arbitrary position. In this case, changes in line segments as points move are displayed in real time as dotted lines. (2) Use the arrow keys on KBDII to move in the vertical and horizontal directions in units of one dot. (3) After inputting any moving dot value on KBDII,
Use the arrow keys on the DII to move each input dot in the vertical and horizontal directions. However, when arrow key movements are performed continuously, the movement amount from the second time onwards returns to the initial value of 1 dot.

The point to be moved is usually only one picked point, but if the attribute of the picked point is an end point, the attribute of the point adjacent to the selected point is an intermediate point, and the X or Y coordinate is If it is the same as the selected point, one or two adjacent points
Like the selected point, the point is also highlighted in black and moves at the same time as the selected point moves.

(A) in FIG. 55 shows a state in which point M to be moved is picked. (B) shows a state in which the picked point M' is being dragged and moved by the PD 12, and a new line segment is displayed in real time as a dotted line as the point M' moves. Next, (C) shows a state in which the moved point M' is fixed at the destination and at the same time the corrected line segment is newly displayed.

FIG. 56 shows a state in which the point E2 to be moved is picked.

At this time, point E2 is the end point of curve EIE2 and curve E2E3, and intermediate points M2 and M3 are located at the same X coordinate as end point E2, so points M2 and M3 are also displayed in reverse black like point E2. .

FIG. 57 shows a state in which the picked point E2' is moved to the right. At the same time, points M2' and M3' are also moved while maintaining their positional relationship with point E2', and the corrected line segment is newly displayed.

FIGS. 58 and 59 are examples in which the moving direction is limited to the X-axis direction or the Y-axis direction.

The procedure for point movement is set using the flowchart shown in FIG. 60 and the editing screens shown in FIGS. 56 to 57.

A movement flag indicating whether or not the sample point has been moved is initially set to OFF in 5 tepl. 5. In step 2, pick one point Pi in the CRT editing area. 5. Turn on the movement flag in step 3. Step 5 is a determination as to whether the aforementioned adjacent points should also be moved. In step 5, PMEM
The point to be moved is determined by referring to the data table shown in FIG. 10 above. This decision follows the decision criteria described above.

In other words, the point to be moved is usually only one picked point, but the attribute of the picked point is end point, the attribute of the point adjacent to the selected point is intermediate point, and the X coordinate or Y If the coordinates are the same as the selected point, one or two adjacent points will also be highlighted in black like the selected point, and will move at the same time as the selected point moves.

In step 5, the next input is received, and in steps 7 to 1 of step 5, the received input is determined. If the result of the determination is that the input is a menu pick, this function is terminated. Also, if it is a normal point power, 5tepH
At step 5, the input is input to point P1, and the processing from step 3 onward is repeated. If the input is any of the items shown in (1) to (3) above, in step 12, P in FIG.
I (x) and PI (y) are changed, display data is recreated, and displayed on the CRT 13 through the VRAM 14. In addition, if the input is undo (right button on PD12), the movement flag is determined in 5 step 13, and if it is ON, the currently displayed outline shape is set as a sample point in 5 step 16. Return to the state before the move,
In step 5, the movement flag is turned OFF. Also 5t
If the judgment in ep13 is OFF, after returning the currently displayed outline shape to the state after moving the sample points,
In step 5, turn on the movement flag. By setting the movement flag to 0N10FF L and retaining the contour data before movement and the contour data being moved in PMEM, 5tep 14.15 and 5tep 16.17 return/restart the previously moved point. Undoing is possible by simply operating the right button of the PD 12.

Next, the point alignment 59-e will be explained below using FIG. 61. This function is called by picking the "point alignment" or "point alignment within area" menu using the PD 12. When this function is called, a line cursor in the Y coordinate direction is displayed on the screen.

Point alignment is a function that moves the X or Y coordinate of an arbitrary sample point to the same coordinate as the X or Y coordinate of the reference point, and at the same time corrects and displays the line segment. To align the points, first select the direction of the coordinate axes to be aligned, that is, X coordinate alignment or Y coordinate alignment. The selection method is performed by displaying a line cursor on the screen and pressing the middle button of the PD 12. When you pick the "Align points" menu, a Y coordinate - horizontal line cursor will be displayed on the screen.
It is possible to move on to the next step of aligning the points in the Y coordinate-horizontal direction in this state, but in order to align the points in the X-coordinate-vertical direction, use the middle button on the PD12 to move the line cursor to the X-coordinate-vertical direction. Do this by changing the display. Furthermore, the same <
The XY coordinates of the line cursor can be switched using the middle button of the PD 12. Next, with the line cursor displayed on the screen, a reference point is selected by picking an arbitrary sample point with the left button of the PD 12.

The selected reference point will be highlighted in black and the same X as the reference point will be displayed.
A line cursor, that is, a reference line, is displayed at the coordinate or Y coordinate. Also, at this time, an cursor is displayed on the cross in addition to the reference line. Note that the position of the reference point (reference line) can be corrected in units of one dot using the arrow keys on KBDIl. Next, select the sample points you want to align other than the reference point. There are two selection methods: picking the points you want to align one by one, and specifying a rectangle and targeting the points within it. This is executed by pressing the middle button of the PD12. At this time, the line segments are simultaneously corrected and displayed. Note that point alignment can be executed continuously with the cross cursor displayed.

FIGS. 61A to 61F are diagrams sequentially showing the steps of point alignment. (A) shows the initial screen when the "point alignment" menu is selected. A line cursor in the Y coordinate direction is displayed on the screen.

(B) shows a screen that has been changed to a line cursor in the X coordinate direction using the middle button of the PD 12. In addition, at this time, PD
Pressing the middle button 12 returns the screen to (A).

(C) shows a state in which the reference point EO is picked with the left button of the PD 12 while a line cursor in the Y coordinate direction is displayed. At this time, the line cursor is fixed as a reference line to the Y coordinate of the reference point highlighted in black, and a crosshair cursor CC is displayed on the screen. (D) shows a state in which the position of the reference point has been corrected by several dots downward.

(E) shows a state in which point alignment has been executed for point El in (D). Place the cursor CC' on the cross at point El, and use the middle button of PD12 to move point E1 to the same Y as the reference line.
The coordinate point El' is moved to, and the line segment is corrected and displayed. (F)
(E) shows a state in which point alignment has been executed for point E2 in (E).

FIGS. 62 and 63 are diagrams showing an example in which points to be aligned are specified by area.

E in Figure 62. is the reference point, 1 is the indicated rectangle, E,,M
, represents a sample point included within rectangle 1, and M2 represents a sample point outside the rectangle. In other words, we have selected E,,M, as the points we want to align.

Of course, it is possible to add or cancel target sample points regardless of whether they are inside or outside the rectangle.

Figure 63 is E. It is a diagram showing where E,,M, are aligned.

The procedure for point alignment is shown in the flowchart in Figure 64-1 and in Figure 6.
This will be explained using the editing screen shown in Figure 1. Initialize by turning off the movement flag indicating whether the movement has taken place in 5 tepl. 5
In step 2, select one point in the CRT editing area, for example E. Input the coordinates of from the PD12. In step 3, a vertical line or a horizontal line is generated as a reference line from the coordinates entered in step 5 according to the vertical and horizontal directions of the cursor, and C is passed through the VRAM14.
Display on RT13. In step 5, the amount of movement specified by the arrow keys on the KBDII is input. 5tep
E at 5. , change P (x) and P (y) in Fig. 10(d) based on the amount of movement of the reference line input in step 4,
The curve parameter table shown in (e) is recreated, display data is created, and displayed on the CRT 13 through the VRAM 14. The reference line is also redisplayed according to the amount of movement.

In step 5, the method of specifying the sample points to be aligned is determined from the input on the PD 12, and a moving point table shown in FIG. 64-3 is created. The moving point table holds the number of moving points (
a), the contour line No. of the moving point, L[i], and the sample point No., P[i], and is composed of MOVETAB, and exists on PMEM. 5tep6 will be explained in detail using the flowchart of FIG. 64-2. 5te
Data from the PD 12 is input at p6-1. 5te
At p6-2, it is determined whether the input is a point pick (left button). If it is a point pick, 5step6-1
In step 2, the picked sample points are registered in MOVETAB. 5tep6-13 accepts the next input, 5t
In ep6-14.6-15, the received input is judged. As a result of the judgment, if the input is a point pick, 5 steps
Repeat the process from 6-12 onwards.

In addition, the input at 5tep6-13 is an execution instruction (PD12
(middle button), end 5step6, and press 5te
Execute p7 and later. If the input at 5tep6-1 is not a point big, then at 5tep6-3 it is regarded as the start of area designation, and the position of the PD 12 at 5tep6-1 is set as the coordinates of one point in the area. Similarly, in step 56-4, the position of the PD 12 is set to the coordinates of the diagonal point of the point designated in step 6-1 of the area. 5 step 6-3. The sample points included in the area determined in 6-4 are P (x) and P in Figure 1O (d).
Search by referring to (y) and register with MOVETAB. At 5tep6-6, accept the next input, and at 5tep
6-7. In 6-8, the receiver judges the input. As a result of the determination, if the input is a point pick, it is determined in 5step 6-9 whether the picked point is registered in MOVETAB, and if it is registered, in 5step 6
- Delete the information of the point picked at 10 from MOVETAB. If it is not registered, register it in MOVETAB in 5step 6-11. Furthermore, if the input at 5tep6-6 is an execution instruction (the middle button of the PD 12), 5tep6 is ended and 5tep7 and subsequent steps are executed.

In step 5, P( of FIG. 10(d) on PMEM is
The amount of movement is determined by referring to X) and P(y), and the images shown in FIGS. 10(d) and (e) before the change are held in the PMEM 6 and are designated as PDATA'. P (x) or P (y
) is set to be the same as the reference point, the curve parameter table in (e) is re-created, the display data is created, it is displayed on the CRT 13 through the VRAM 14, and the movement flag is turned ON. FIG. 61(E) shows the state after the movement. In step 5, the next input is accepted, and in steps 9 to 11, the accepted input is determined. As a result of the determination, if the input is a menu pick, this function is terminated. If there is no normal input, the point is set as a reference point in step 5 step 12, and the processing from step 3 onwards is repeated. In addition, 5t
If the input in ep8 is undo (right button on PD12), determine the movement flag in 5step13,
If it is ON, the display is returned to the state before the point was moved in 5tep14, that is, the data of PDATA' held in PMEM6 in 5tep7, and then the display is redisplayed in 5tep1.
Step 5 turns off the movement flag. If the movement flag is OFF, display the PDATA data changed in 5step 7 in 5step 16, that is, the state after movement,
5. Turn on the movement flag in step 17.

By setting the movement flag to 0N10FF, PMEM6
You can switch the display of PDATASPDATA' above, and by doing so, the point moved once is retained as PDATA (after movement) and PDATA' (before movement) on PMEM6, and the current status can be seen by the movement flag. Therefore, it is possible to return the point once moved in 5tep 13.14 and 5tep 15.16 or to move it again by simply operating the right button on the PD 12.

1 Rough View ■ Method Next, 89-f contour line deletion in FIG. 4 will be explained using FIG. 67 (illustration of contour line movement) and FIG. 65.

This function is activated by picking the "contour line deletion" menu with the PD 12.

Contour line deletion is a function by which the operator erases any contour line on the editing area. If Ll in FIG. 67 is deleted, the result will be as shown in FIG. 65.

The procedure for contour line deletion will be explained using the flowchart of FIG. 66. Initialize the flag “Erase FLAGJ” to OFF to indicate whether the outline was erased at 5tepl.5te
In p2, the contour line is input from the double-click information of the point from the PD12. 5 step 3 to create the outline in VRAM1
The data is erased from the CRT 13 through step 4, and the erase FLAG is turned on in step 4. In step 5, the next input is accepted, and in steps 6 to 8, the accepted input is determined. As a result of the determination, if the input is a menu pick, this function is terminated. Also, if it is a normal contour input (double-clicking a point on PD12),
The input is set to L, and the processing from step 3 onward is repeated. In addition, the input of 5tep5 is und.

(Right button on PD12), 5 steps
The erasure FLAG is determined at lO, and if it is ON, the contour line is displayed at 5 tep, and the erasure FLAG is turned OFF at 5 tep12. Further, if the determination at 5teplO is OFF, the contour line is erased at 5tep13, and the erasure FLAG is turned ON at 5tep14.

Through the steps 5tep11.12 and 5tep13.14, it is possible to erase and redisplay the contour line that has been erased by simply operating the right button on the PD 12.

The movement of the elm and ILIL contour lines will be explained using FIGS. 67, 68, and 69. Contour movement is activated by picking the "contour movement" menu on the PD 12.

Contour movement is a function that moves one or more contour lines of a character or a specified section by an arbitrary amount in an arbitrary direction or in any one of the xSY directions. FIG. 67 shows the character data before movement. FIG. 68 is an example in which the two outlines constituting the character rDJ are moved in arbitrary directions, and FIG. 69 is an example in which 1 is moved in the X direction in the section of FIG. 67.

The procedure for moving the contour line will be explained using the flowchart in FIG. 70. At 5 tepl, initialize "movement FLAGJ", which is a flag indicating whether the contour line or section has been moved, to OFF. At 5 tep 2, input the first point from PD 12. At 5 tep 3, the input to PD 12 at 5 tep 2 is the contour line instruction ( If it is a contour line instruction, the contour line to be moved is further input in step 21 and 22 until the end is instructed.

In 5tep3, if it is not a contour line instruction, 5tep3
The PL input at p2 is regarded as the section end point, and the other section end point is input from PDI2 at 5tep4. 5tep
In step 5, points on the section are input, and in step 5, the moving section is determined.

At 5tep7, accept the next input, and at 6tep8~11
At the receiver, the input is judged. As a result of the determination, if the input is a menu pick, this function is terminated. In addition, in the case of normal point strength, the input is set as the first point input in 5tep12, and the processing from 5tep3 onward is repeated. In addition, if the movement amount and movement direction are specified using the arrow keys or numeric keys on the KBDII, or the movement destination is specified by dragging the PD12, the display data of the outline or section is re-created in step 5, and after being moved to the CRT 13 via the VRAM 14. Display data. 5step1
Turn on the movement FLAG with step 5.

In addition, if the input of 5tep7 is undo (right button of PD12) (judgment 5tepH), 5tep1
The movement FLAG is determined in step 6, and if it is ON, the state before movement of the contour line or section is set to V in step 5 step 17.
Display on CRT13 through RAM14, 5tep1B
Turn off the movement FLAG with . In addition, if the determination in 5tep16 is OFF, in 5tep19 the state of the contour line or section after movement is transferred to the CRT1 through the VRAM14.
3 and turn on the movement FLAG in step 20. 5tep 17.18 and 5tep 19.20 above
This makes it possible to restore and re-move previously moved contours and sections simply by operating the right button on the PD 12.

Further, the function of moving the contour line or the section in either the X direction or the X direction is realized by referring to the type of input data in 5tep7 in 5tep14.

Karudan Toyo l and Next, virtual line generation 59-h in FIG. 4 will be explained.

Concept Description Virtual line generation is a function that allows an operator to arbitrarily create (generate) a contour line on a variant area, in addition to character contour data. After completing this function, the created contour line can be changed to any shape by performing various changes similar to normal contour lines, such as point insertion and point movement, in other functions. I can do that. The difference between virtual lines and character outlines is that virtual lines are used only for character creation and are not recognized as character outlines.
It is not stored in the font data file even "at the time of registration/termination".

The main purpose of using virtual lines is to use them as templates (underlays) when editing contour line data, etc., and to create curved parts that appear continuous, such as section El-E2 and section E3-E4 in Figs. 71 and 72. The purpose is to easily check or edit the design of curves.

As mentioned above, the contour shape initially generated as a virtual line can be changed freely like normal contour data, so it may be a rectangle or a circle, for example, but in this embodiment, a preferable example is as shown in FIG. 74. It uses an arc shape.

Explanation of Flowchart The procedure for generating a virtual line is shown in the flowchart of Fig. 73 and Fig. 7.
This will be explained using the editing screen shown in Figure 4. At 5 tepl, the flag [Display FLAGJ] indicating whether or not the arcuate figure is displayed is initialized to OFF. In step 5, the coordinates of one point, for example 11, in the CRT editing area are input using the PD 12. Next, in step 3, for example, the coordinates of I2 are similarly input. In step 4, from the coordinate values of I1 and I2, the arcuate figure Y
Calculate the contour data (sample point coordinates) of 1. The contour line Y1 is composed of end points El and E2 and intermediate points M1 and M2 as shown in FIG. 74, and the coordinate values of these sample points are calculated as follows.

E1x=11x E1y=11y E2x=I2x E2Y=I2M M1x=11x+ (I2x-11x)*KM1y=1
1y M 2 x = I 2 x M 2 y = I 2 y - (12y - I 1
y ) * K Here, K is a constant held in the program memory 6, and is 0.55 in the case of FIG. 74. The contour line data Yl calculated in this way is
After displaying on CTRL3 through the VRAM 14 in step 5, the display FLAG is turned ON in step 5. 5
In step 7, the next input is received, and in steps 8 to 11, the received input is determined. As a result of the determination, if the input is a menu pick, this function is terminated. Further, if it is a normal point strength, the input is set as the first fish input in 5tep12, and the processing from 5tep2 onward is repeated. Also, invert instructions (middle button on PD12)
If so, calculate the inverted figure Y2 of the arcuate figure Y1 obtained in 5tep 4), delete the currently displayed arcuate figure Y1 in 5tep 14, and replace the arcuate figure Y2 with the data of the arcuate figure Yl in 5tep15. ,5te
Return to p5. That is, the inverted figure Y2 on the side indicated by the broken line in FIG. 74 is displayed. In addition, if the input at 5tep7 is undo (right button on PD12) (judgment 5tepH), the display FLAG is determined at 5tep16, and if it is ON, the currently displayed flag is determined at 5tep19. Delete the arcuate figure Y1, 5 steps
At step 20, the display FLAG is turned off. Also, 5tep
If the judgment in step 16 is OFF, display the sample point data of the arcuate figure Y1 in 5tep17, and then
Turn on the display FLAG in p18. Above 5 step 1
7.18 and 5tep19.20, it becomes possible to erase and redisplay the arcuate figure that has been created just by operating the right button on the PD 12.

The 39-i regular arc in FIG. 4 for the LH ball will be explained using FIG. 75.

This function is called by picking the "regular arc" menu on the CRT 13. This function is for CRT1
This provides a means for easily changing the shape of the curved portion of the contour line displayed on the editing area No. 3 into a circular arc or an elliptical arc. Here, for curved parts such as circular arcs and elliptical arcs, this device performs B-5 line approximation, and automatically generates control points for that purpose, creating mathematically rigorous circular arcs and elliptical arcs. Not that I will.

The operating procedure will be explained using FIG. 78.

Set the unevenness flag to 1 in 5 tepl. 5. In step 2, input the end point PI of the sample point on the figure. Next 5 step 3
Input the adjacent end point P2 on the same contour line. Pl, P2
In step 4, sample points are calculated to generate a new elliptical arc for the curve in that section. When the coordinates of PI are (Elx, Ely) and P2 are (E2x, E2y), the method for calculating the intermediate point is shown below.

By the X coordinate of the end point E1 and the X coordinate of the end point E2, intermediate points M1 and M2 are generated as shown in FIG.
Replaced with sample points between ~82.

Coordinates of generated intermediate points M1 and M2 (Mix, Mly)
and (M2x, M2y) are calculated by the following formulas, but which formula to use is determined by the unevenness flag shown in FIG.

M 1 x = E 1 x + (E 2 x −E
l x )・K or ElxM1y=E1y or E2y
+ (Ely-E2y)・KM 2 x = E 2
x or Elx+ (E2x-Elx)・KM2Y=E2
y+ (Ely-E2y)·K or E2Y where K is a constant held in the program memory 6. In this way, the circular arc or elliptical arc in the cases of FIGS. 77(A) and 77(B) can be easily generated.

Next, in step 5, the curved portion C1 is displayed. 5tep
The next data N is accepted in step 6, and the determination is made in steps 7 to 10, and if N is a menu pick, the process ends. Further, if N is the input of the end point P1, return to 5tep3. If N is an instruction to change the unevenness, a sample point with changed unevenness is calculated in 5tep13, the resulting figure is set as C2, 01 is deleted in 5tep14, and CI is set to 02 in 5tep15. Next, if the unevenness flag is 1, set it to 2. If it is 2, set it to l. L/ (step
16), return to step 5 and display the CI.

When N is an undo instruction, CI is erased and the original figure is restored (step 12). Then, return to step 5 and accept the input of the next data.

Next, the generation of the figure 59-j will be explained using FIG. 79. This function is called by clicking the "Figure" menu, and it is possible to easily create shapes such as perfect circles and regular polygons.

Whether to create a perfect circle or a regular polygon is selected from a submenu on the CRT. In this device, all curves are expressed using B-splines, so even when creating a perfect circle, parameters that express the circle must be stored in the form of center coordinates (x, y) and radius R, for example. without doing it,
Automatically generates 15 plins of control points that are necessary and sufficient to approximate a circle. To create a perfect circle, set the center of the circle, for example Ll, and any point on the circumference, for example L2, on the editing area.
The method indicated by D, two points that are the diameter of a perfect circle, for example, Ml,
There are two methods: specifying M2 and inputting the center coordinates and radius using the keyboard. When instructed by PD, the perfect circle determined by L2 or M2 is determined by the movement of FD,
It is also updated on the CRT. In the case of creating a regular polygon, the determination of the regular circle is regarded as the creation of a polytangent circle, for example cl, of the regular polygon, and the number of angles is input after determining the regular circle.

Next, regarding the center movement to 59- in Figure 4,
This will be explained using figures. This function can be called by "Center"
This is done by picking the menu.

Center movement is a function that displays the body frame and baseline as shown in FIG. 80, and changes the positional relationship between the body frame and all contour lines using the arrow keys. If the object to be processed is in italics, an italic body frame is displayed as shown in FIG.

The procedure for moving the center will be explained using the flowchart shown in FIG. 83 and the editing screens shown in FIGS. 80 and 82. 5te
The flag “Moving FLA” indicates whether the center has moved in pl.
Initialize GJ to OFF. In 5 step 2, to make it easier to set the center, remove the virtual line and display the original
FF, sample point display OFF, curve display, contour line display (
The cRT 13 displays the cursor display OFF (fill 0FF), cursor display OFF, and blank state through the VRAM 14. 5tep
In step 13, the body frame and baseline are displayed from the character information on PMEM in the same way as in step 2. At this stage, the editing screen appears as shown in FIG. 80. KBD with 5tep4
Input the movement direction data using the arrow keys on the II. In step 5, based on the data input in step 4, the body frame and the baseline are displayed moving instead of the entire contour line in order to speed up the display. When moving the center, it is only necessary to know the relative positions of the body frame, baseline, and contour line as part of the process, so there is no problem with this.

Further, in step 5, the movement amount is held in PMEM.

5 step 6 accepts the next input, 5 step 7 to 10
At the receiver, the input is judged. As a result of the determination, if the input is a menu pick, this function is terminated. In addition, if the input is a movement direction instruction using the arrow keys, turn off the movement flag in 5step18, and
Repeat the process from step 5 onwards. If the input is the return key on the KBD 11, in step 11 the sample point coordinates of all contour lines are changed as follows from the movement amounts dx and dy held in the PMEM in step 5.

Px [i] =Px [i-dxPy
[ico = Py [i] -dy The contour line data changed in this way, the body frame and baseline before moving in step 5 are displayed on the CRT 13 through the VRAM 14 as shown in Fig. 82, and then the FL is moved in step 5.
Turn on AG and return to step 5.

In addition, if the input of 5step6 is undo (right button on PD12) (steplO), 5step1
3 determines the movement FLAG, and if it is ON, 5te
Return to the state before movement on p16, and move F on 5tep17
Turn off LAG. Also, the judgment of 5tep13 is O
In the case of FF, return to the state in which it was moved at 5tepH, and
Turn on the movement FLAG in step 15. 5 steps above
14.15 and 16.17, it is possible to restore/remove contour data that has been moved by simply operating the right button on the PD 12.

■ The undo/redo menu is the undo/re mentioned above.
d.

The process is set up as a menu and its function is displayed. For example, when this menu is picked with one of the other menu Pick etc. of the end process of 5tep6 in Fig. 31, 5tepl 1 to 12 of Fig. 31 Similar processing is performed to realize undo-redo.

Next, the point coordinate display of FIG. 4, 5IO-a will be explained with reference to FIGS. 84 and 85.

Point coordinates are the coordinate values of sample points of font data,
With two coordinate systems (absolute coordinates and design coordinates), you can display the coordinate values in the echo area by picking a sample point on the editing area, or check by displaying a list of all sample points. This is a feature that can be used.

Next, the procedure for displaying point coordinates will be explained using the flowchart of FIG. 85.

At 5tepl, menu-4 all sample points and menu'-5
Display the coordinate system switching menu. At step 52, input of the next data N is waited, and if N is a sample point pick, the picked coordinate values are displayed in the coordinate area at step 4. Display in the coordinate area will be described later.

If N is the pick of menu 5 in 5step 5, 5te
At p6, switch the current coordinate system from absolute coordinates to design coordinates. This menu is a toggle menu. If Table 1 is displayed at this time, the coordinate values displayed there are also rewritten. If N is Menu 4 selection, Menu 2 for scrolling Table 1, Menu 3 for terminating, and Table 1 displaying a list of all sample points are displayed. Table 1 displays point number, fish debris, X coordinate, and X coordinate in this order. If all sample points cannot be displayed in this area at once, refer to the next page using the scroll menu. N input is 5tep9
If you pick menu 2, scroll Table 1 (step). Display the previous item ↑, display the next item ↓
It is expressed as. When selecting the end menu or other menu picks, perform the end process (step 12) and end.

The termination processing includes processing for returning the menu and erasing Table 1 if it is displayed.

The echo of the coordinate values of the coordinate area will be explained using FIG. 86.

The coordinate values of the picked sample points are displayed in the following way: 86-1 indicates the echoed coordinate numbers 1 to 4, and the coordinates of the picked sample points are displayed as 86-1 for X according to the current coordinate system -2 column, 86- for y
The echo of the next coordinate will be displayed in the 4th column starting from the top. When the 4th column is displayed, the echo of the next coordinate will be set to 4th, and the coordinate value that was in 4th will go to 3rd and so on. Scroll down
, 86-3 and 86-5 display the difference from the previous echoed point, which allows the distance between the two points to be determined. Echoing to this area is performed not only for the point coordinate menu function, but also when picking sample points for other character production. 86-6 is a toggle menu for whether or not to echo the coordinates in real time, and when it is ON, the area 86
-7, the coordinate values when dragging the sample point are displayed in real time.

History of Prisoners The list will be explained using FIG. 87.

The list is a function that displays information about the typeface to which the character belongs and information other than the sample point coordinate values of the character for the font data currently being modified. 87
-1 is an area that displays information regarding the font, and 87-
2 is an area where the value of each character information is displayed for each item, with the value before correction and the current value side by side.

In addition, the main one-plate carpenter character information is not font data such as the sample point coordinates and drip characteristics that make up the character, but rather information such as the height and width of the character, not values common to the font, but the character unit. refers to the information related to the coordinate system of characters that have specific values.

In other words, character information can have a value common to the entire typeface as a default, or can have a unique value for each character. In other words, there is information that cannot be set for each character and has a fixed value for the entire font.

Character information input is a function to input character information that can be set for each character as described above, and the value set here is stored in the font data file and is sent to the DI along with the font data.
Stored in SK3.

The procedure for inputting character information will be explained using the flows shown in FIGS. 88 and 89.

When you pick the menu for inputting character information, the menu for inputting character information is displayed in 5 tepl (Figure 88).
88-1 in Figure 8 is YES, which indicates the result of character information input.
There are three menus: , No, and End, and 88-2 is a table of menus for inputting each character information name and its value. 5te
At p2, turn off the data input flag and wait for the input of the next data N at step 3. If the next data N is a menu pick at step 4, proceed to 5step 5, and then input the next data N.
If is a value input menu, turn on the data flag and 5
Return to step3. When N is not a value input menu, turn off the data input flag L (step 6), 5step 8
If it is a No menu pick, the newly set input value is returned to the value before the start, and the process returns to step 3. If it is a YES menu pick, check the currently input value and register the setting value (5tepH) 5t
Return to ep3. 5tep12.5tep13 when N is the end menu or another menu, 5tep14 is 5tep
l Check the input value as in 1, register the set value, and finish.

If N is outside the menu pick in 5step 4, 5step 15
If N is the key human power from KBDII, then 5tep1
Proceed to step 6, and when the key is the return key, turn off the data input flag to finish the input, and return to step 3.
If the key is not the return key, go to step 5 step 18, and if the data flag is OFF, do nothing and return to step 3, but if it is ON, go to step 19, echo the input value to the value input menu,
Perform data input processing and wait for the next data input in step 3. In other words, the input value from KBDII can be set in the value input menu only when the data input flag is ON, and the value input menu can be set by picking the value input menu. , only while the return key picks another menu. Also,
During that time, the data N input in step 3 will be echoed one by one to the value input menu.

iOtsuno and 1 Figure 4 5ll-6 Line setting Line setting is a function that allows the operator to set and display multiple auxiliary lines on the editing area, separate from the character outline data, and these auxiliary lines are called lines. , the line has, for example, X
A wind-in parallel to the axial direction and a wind-in parallel to the y-axis direction can be set.

The line set here can be displayed or hidden at any timing during the production of each character using the line ON/OFF menu of the display control menu described above.

In addition, the set line information can be changed to the DI for each operator.
It is registered in SK3 and can be loaded and referenced on PMEM6 as appropriate unless the settings are changed or deleted.

The main purpose of lines is to serve as auxiliary lines as a reference for determining the size, height, width, etc. of individual characters when creating characters.By determining these auxiliary lines for the entire typeface, it helps to balance the overall character. You will be able to arrange the following.

The line setting procedure will be explained using flowcharts shown in FIGS. 90, 91, and 92.

Picking the line setting menu indicates the line setting result, as shown in FIG. Menus 90-1 for YES, No, and End, and a table 90-2 for menus for inputting line name, position, and display state switching are displayed.

In 2, the alphabets A-LSa to e in the symbol field correspond to lines A-L and a-e in the editing area, with A-L used to set the horizontal line and a-e used to set the vertical line. do. In other words, the values entered in the position input menu field are the X coordinate value for A-L, and the value for a-L.
For e, input the X coordinate value. The display state switching menu column is a menu for switching the display flag for each line to display or hide the set line, and when the line is being displayed, the line is displayed in the editing area.

At 5 tepl, only lines whose display flags are set to ON are displayed in the editing area according to the current setting state.

5Turn off the data input flag in step 2, and
In step 3, input the next data N. If N is a menu pick in 5 step 4, 5 step 5. If the menu picked in 5 step 6 is a name input menu or a position input menu, turn on the data input flag in 5 step 8,
5 Return to step 3, wait for next input, otherwise 5
Proceed to step 9. If N is the display switching menu in step 9, the display flag of the picked line is 0N1.
Switch 0FF and return to 5tep3. If N is a NO menu, return the newly set line name, position, and display flag to the state before the start in 5teplo, and return to 5step3. If N is a YES menu, change each line, body frame, etc. according to the display flag in 5step14. Display in the editing area and wait for the next input in 5tep3, N in 5tep15.16
When is the end menu or another menu pick, the currently input setting value is checked and registration is completed. 5te
p18 to 21 are the processes when N is not a menu pick. When using the return key manually, turn off the data input flag at 5 step 19, mainly process the input by KBDII, and end the input, and when using anything other than the return key at 5 step 18. When the data input flag is ON, that is, data input is possible, the input value is actually echoed to the menu area in step 21 and input processing is performed, and the process waits for the next data input again in step 3.

FIG. 91 shows, as an example, a state in which the lines in the symbol field a are set. For the line set here, line ON/

Instructions for the above menus are provided by PD12 or KBDI.
This shall be done in accordance with I.

The font data file name list of 97-1 is created by searching DISK 3 when starting printer output.

First, outline display will be explained.

To display the outline, specify the character code range in Fig. 97-3 and select ASB, C, or D in Fig. 97-5.
This is done by picking at D12.

The contents of the ASB, C, and D displays are shown below. That is, A
The outline is 1/2 of the data in the font data file.
For example, if the data in the font data file is defined as 800 x 800 dots, it will be displayed as 400 x 400 dots, which is used for a rough quality check, and B is the same as A. However, C shows the inner outline as a dotted line, and C shows one dot of data in the font data file corresponding to one dot of the printer, but at this time, solid lines are drawn between the sample points. The contour line is displayed as a dotted line, and line width information, which is publicly known to prevent quality deterioration at a specific character size, is displayed along with its parent-child relationship. D is used to confirm the validity of information, and the display size is the same as C, but the sample points are shown with dotted lines and the outlines are shown with solid lines.

The outline display processing procedure will be explained using the flowchart of FIG. 101 and the output example of FIG. 98.

At 5 tepl, the start and end codes specified in FIG. 97-3 are held in PMEMS. In 5tep2, the outline type selected in FIG. 97-5 is held in PMEM6. 5 Repeat the process from step 3 onwards. 5tep
In step 3, read the font data from the start code to the end code held in PMEM6 from the font data file of DISK3 in 5 tepl, and write the first
It is stored in the format shown in Figure 02. In step 5, it is determined whether the end code has been output or there is no more data in the font data file, and the outline display process is ended. At 5tep5, the outline type held in PMEM6 at 5tep2 is determined, and if it is C or D, scaling is applied to FIGS. 102(a) and 102(b) on PMEM6 at 5tep6. In step 5, display data is created and stored in the PMEM 6 with reference to (b). In step 5, the outline type is determined again, and in the case of C, in step 9, a line segment representing the parent-child relationship of the line width information is generated based on the data in FIGS. 102 (b) and (C), Hold in PMEM6. At 5 teplo, the sample point coordinate values and debris characteristics shown in FIG. 102(b) are converted into outline display data (line segment string data), and the data is stored in PMEM6. 5tep
In H, the data created with 5tep7.5tep9.5teplo and held in PMEM6 is sent to 10 and PRT9
The diagram shown in FIG. 98 is then output.

Next, the filled display will be explained.

For filled display, specify the character code range in Figure 97-3, enter the point size range in Figure 97-97-6, and select the "Quality Inspection" or "Center Inspection" menu.
This is done by picking at D12.

The contents of the display for “Quality Inspection” Center Inspection are shown below.

In other words, "quality inspection" involves generating so-called typesetting using a font in the same condition as the product at a specified point size and using it for quality inspection, and "center inspection" involves using a font in the same condition as the product at a specified point size. It is the size and is displayed in letters for center inspection, sandwiched between them.

The processing procedure for fill-in display will be explained using the flowchart in FIG. 103 and the output example in FIG. 99.

Enter the output character code range in 5 tepl and select PMEM6
to hold. In 5tep2, the output point size is input and held in PMEM6. Figure 97 in 5step 3
Is the menu selected in 7-6 “Quality Inspection”?
Whether it is a “center inspection” is held in PMEMS. 5
The processing is repeated for the designated point size for steps 4 to 5 and step 9. 5tep4.5 is the above-mentioned figure 101 5t
Similar to ep3.4, font data is read from DISK 3, and a decision is made as to whether or not to finish. In 5tep6, 5te
The output type instructed in p3 and held in PMEM6 is determined, and in the case of ``center inspection'', a pattern for inspection is created in step 5.The pattern is as shown in Figure 99 Center inspection (for example, O ,N, etc., or a pattern such as a square.In 5tep8, 5tep

Image data is created from ATA, taking line width information into consideration. In 5tep9, once the 5te held in PMEM
The data created in p7.8 is sent to 10 and outputted from PRT9 as shown in Figure 99.

Finally, character information output will be explained.

Character information is output by specifying a character code range in 97-3 in FIG. 97 and picking 97-7 in FIG. 97 with the PD 12. The character information displayed here is shown in FIG. 100, for example.

Character information output will be explained using the flowchart in FIG. 104. At 5tepl, the start and end codes specified in FIG. 97-3 are held in PMEM6.

In 5tep2, DI the font data from the start code to the end code held in PMEM6 in the previous 5steps.
Load from SK3 font data file and PME
It is held in M6 in the format shown in FIG. In step 3, it is determined whether the end code has been output or there is no more data in the font data file, and the character information output process is ended. In step 5, referring to FIG. 102(a), the data is formatted and output to the PRT9.

Refer to FIG. 110 for step numbers.

First, a file name to be compared is input (Sl).

Next, the display of the processing code is set in step S2.Finally, a function is selected and executed in step S3.

Features include compression and expansion. For compression, as shown in FIG. 111, first the data in state A is arranged in coats so that there are no gaps, and is brought into state B. Finally, the unused area is released, and the file is compressed as shown in C. Expansion changes the size of the data section. As with compression, set it to state B and specify the size of the expansion using the number of characters. If the number of characters is positive, it is 1 in the state of C.
Expand by the average number of blocks of characters x number of characters. If it is negative, the size will be reduced from the state of B by the average number of blocks x number of characters. However, it does not become smaller than state C.
