Abstract

PURPOSE:To simply change a graphic pattern by changing the attribute of a required sampling point and forming the graphic pattern based upon the changed attribute. CONSTITUTION:Point attribute inversion is a function for inverting the attribute of a selected sampling point, i.e. an end point is changed to an intermediate point or an intermediate point is changed to an end point, to correct a contour line. When an optional point in a CRT edition area is picked up, a point attribute indicated by Fig.(b) stored in a PMEM 6 is referred, an end point and an intermediate point are inverted and a parameter table indicating a curve in Fig.(d) is changed. Data in Figs.(a), (b), (c) are worked as display area and a changed contour line is displayed on a CRT 13 through a VRAM 14. Consequently, a graphic pattern can simply be changed.

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, and printers, it is common to use character cents (font) in l typeface units.
For this reason, it is necessary to prepare a very large number of character data.Especially in the case of Japanese fonts, each font must contain at least about 6,500 characters as specified in the JISXO208r Kanji Code System for Information Exchange. Moreover, unlike the bitmap method, the method of expressing characters using outline data has the advantage of being able to output characters of any size using a single type of character capital, so the outline character data used as the character capital has the ability to improve the aesthetics of the character. In some cases, stricter designs than analog original characters are required to maintain the same character.

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, the graphic processing described above has the following problems. Conventionally, attributes have been set for sample points representing graphic patterns, but there has been a problem in that some or all of the attributes cannot be changed with a simple operation.

[Purpose] In view of the above points, an object of the present invention is to easily change attributes set for sample points representing a graphic pattern, and to easily change the graphic pattern accordingly. The purpose of this invention is to provide a graphic processing method that allows for

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

The original data is the outline of the image data read in 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.

Correction work such as point deletion and point movement performed by the operator using the PD12 is shown in Figure 1O (a), (b), (cl), and (e).
This is achieved by referencing/changing the .

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, the file creation Sl 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 the DISKS shown in FIG.

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

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 Deciquiz, m a n
ag efile is prepared. m a n
The ag e file is a matrix of the number of pages x the number of characters, and a flag for the completed step 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
2 and pick b-5, the screen moves to Figure 15, and by picking an arbitrary page number and selecting YES, initialize the managefile flag for that page.
You can cancel the Deciquiz on that page.

By picking b-6 with the PD 12, the deciquiz ends, and when digitizing is started again, the step continues 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 f i 1 e is initialized, and all the menu columns 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). If there are scans 1-5, I
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 from PDI2 (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 the DISKS is also deleted (step 6).

Finally, update the manager (step 7) and end.

・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 procedure for setting the coat will be explained using the flowchart shown in FIG. 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 has a code set (step 3), the number of set characters is reduced by 1 (step 4). When the code is set manually from KBDll (step 5),
p7) The character corresponding to the character coat 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 coating system is JIS and the coating 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
Court settings 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 1).

This will display the picked image data (s
step 2), the cursor of the PD 12 changes to a crosshair cursor (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 PD22.
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 O), the manage file is updated and the process ends (step H).

- 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 horizontal frame, and has functions such as deletion outside the horizontal frame, which turns off all people outside the frame, and a function to turn on or off the inside or outside of a specified rectangle.

External deletion is performed by turning b-15 pink with PD12 (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 PD12.5
step 9), perform noise removal (step).

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) to update the managefile and end the process (step 2).

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 a font, and a typeface with many curved parts such as a cursive typeface. 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 (X1%Y1) 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, IMS
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. The basic screen has, for example, 1280×1024 pixels and 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 X1y 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 scrolls up.

A-4 is a menu 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 from FIG. 30(b) to FIG. 30(f).

Each menu process is basically terminated by another menu entry. 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.

Each display control is not exclusive; for example, a combination of zooming and scrolling 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.

In character correction work 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.
6, and in PMEM6, DIS
It inputs data from K3, changes and processes data already on PMEM6, transfers the data to VRAMI4, and displays it on CRT13.

undo leprosy red.

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.
The und is used as an input to execute the do-redo operation, and is to be performed in each processing procedure.

and redo (undo of undo), or by providing a menu for undo and redo, which will be described later, and when selecting the menu, undo and redo are 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 its implementation, and the figure data table is a table storing the figure data in FIG. 10, and the number l 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 if in step 4 the next data N is an operation that instructs to change the figure data Fi, for example, to delete one vertex of figure F1, then in step 7, figure F1 is is not stored in the undo table, the Fi
, store the data of Fl 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 in 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 Fl has already been 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.

In addition, when there is an undo instruction again in 5 tep 5, in the process of 5 tepl 1, all figures Fi in the undo table will be exchanged again, so redo will be performed. /redo will be repeated.

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 N1, and if N1 is not in the 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 a portion having each function of character data correction of $9 in FIG. 33- is the part having each function of display control of N8 in FIG.
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 that a request is made to 33-4 to change the display due to font data change, and 33-d indicates that 33-4 actually changes the VRA from 33-4 to CRT 13.
This means that a display request is made through M+4. To explain the flow a little more, if there is a change in font data during character data correction work in 33-1, 33-3
A data change request 33-a is issued to 33-3, and after actually changing the font data, a display change request 33-c is issued to 33-4. 33-4 refers to the font data, creates display data, and sends a display request to the CRT (33-4).
3-d) Display. If there are display change requests from the 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
This will have no effect on other processes.

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), the font data, original data, line data, and these data are set as one set, and the number assigned to that data, the display magnification ratio S, the display reference point coordinates 01, and when dividing the curved part of the font data into straight lines. 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 when displaying at 5 tepl. In step 5, input the coordinate O that will be the display reference after zooming. The parameters of S10 are generally the same as those required when performing coordinate transformation from the absolute coordinate system to the display coordinate system. 5tep3 curve division interval N
Enter. In step 4, the font data already on P M E M 6 is converted into coordinates using S and O, and the sample point data of the font data is obtained as shown in Fig. 10 (d).
From this, data for displaying sample points (Fig. 35C) is created.

In step 5, the sample point display data created in step 4, the coefficients in FIG. 10(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 in FIGS. 10(a) and (b). Further, DDATA in (C) is the coordinates PO(X), Po(y) to Pn-+(x), P of the sample point in FIG. 1O(d).

(y) is a value that has been coordinate transformed for display, and for point attributes, L means the line start point, C means the curve start point, and in the case of C, the area where the curved part is expanded into a short vector. The address of (d) is shown below. (d) stores the number npt of point coordinates and npt coordinate values.

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.

At step 5, the display format ST is input. ST is D
Valid only when T=1, takes three values; when 5T=1, DDATA curve display; when 5T=2, DDATA straight line display; when 5T=3, pDATA sample point display . That is, when displaying a curve, in (c), when the point attribute is C, addr2 is referred to, and data connected by line segments in order including the short vector data in (d) is used as display data. When displaying a straight line, only Cc) data,
Display data is data in which only sample point coordinate data is connected in sequence.

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.

In 5tep12, the area in which the display pigs created up to 5tep are to be displayed is input. The WD may be a window.

In 5tep13, if the VRAM can have a plurality of planes, a PL indicating the display destination plane is input. If there is only one plane, 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, PL, DSi: Therefore, it is expanded into a human map on the VRAM 14 and the process ends. 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 thought of as having one for each display destination area WD.

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

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

The scroll of 1 Kutan 2 匪 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 O'
Enter from II. 5 step 4 is the input for display processing, each No., DT, ST, SPF, and WD.

Set up PLSDS. 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=0, n-1) in advance for the current display state for that number.
It shall also be stored on PMEM, and DTX
Substitute the current values for ST, PF, and Pi, and ~■
D is substituted with WD' of 5tep2, deletion is substituted with the display flag DS, and the display is erased by the above-mentioned display processing in 5tep5. 5tep6 is 5t for all data types (n)
There is a part that determines whether to repeat ep4.5, and if there is still data in the display state, it increments 1 in step 5 and repeats step 4.5 again.

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

In step 5, for the display data number No., the scale 81 reference point O1 curve division interval N required for display data creation is input. Reference point 0 is O' input in 5tep3
For S and N, the current values for display data number No. are substituted.

In step 9, create display data according to the display data creation procedure described above, set i=0 in step 5, and
In tepl l, input values necessary for display processing are set.

For DT, , 5TXPFXPL, the current display state corresponding to No. is substituted, WD', which was input in step 2, is substituted for WD, and the display is substituted for DS.

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'), and the display data type is font data, so n=1. For PF and PF, no filling is specified.

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, O' input, and S' input sections 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 5, change the cursor shape to a long crosshair cursor. The cursor will be explained later in step 3.
to display the display center. Step 5: Wait 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 at 5tep6, the input of the next rectangle point P2 is waited at 5tep8. 5t
If the input Nd is another menu in ep9, the process ends after the end process, and if the undo instruction (steplO) is issued, P1 is canceled (5tepH) and the process returns to step4. 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 step 514, WD', S', and O' are new inputs, and the above-mentioned display processing is performed, and the process ends.

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

5tep6.5tep7 When inputting Nd, for example, a left button click is used as a Pl input, and a middle button click is used as an input for magnification. 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.

FIG. 41 shows the zoom processing screen, where 411 is the display center, 41-2 is a long crosshair cursor, and 41-
3 shows the appearance of a rectangular echo, and FIG. 42 is a diagram zoomed in accordance with the instructions by Pl and P2.

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

U osu Explain standard sizes.

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

In the display processing section described above, the initial scale S is input to S. , O as the initial reference point O8 and the area WD' as new inputs.

Original ON/OFF 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. 4-F (WD') in the display processing section (b).
) WD' can be achieved by specifying the display destination area, DT←2, and setting and inputting DS←Hide if the original is currently being displayed, and DS←Display if it is currently not being displayed. It goes without saying that by changing the PL when displaying the original display data, it can be displayed on a plane different from the font display data and viewed overlappingly.

Sample 1, ON/OFF Sample point ON-OFF will be explained.

This menu is also a toggle menu. Display processing section (b
), No4-F(WD'), DT←1.5T-3
All you have to do is enter.

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

1. This menu is also a toggle menu. Similarly No4-
F(WD'), PF-ONi:L, Ds←Display/erase is switched and displayed each time a menu pick is made.

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.

The line 0N-OFF line, for example, the auxiliary line will be described later. Here, regarding the line set while displayed in the line setting menu,
This function can be displayed or hidden by picking 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 0N-OFF The cursors to be switched here are the long crosshair cursor shown in Fig. 46 (a) and the short hair cursor shown in Fig. 46 (b).When ON, the long crosshair cursor is displayed, and when OFF, the short crosshair cursor is displayed. Show vines. 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.

voyage 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 regarding the character pigs in PMEM6 were referenced, the data was processed for display based on the current display state, and the data was expanded on the VRAM14. After that, it is displayed on the CRT 13i.

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 59-a in Figure 4, Figure 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, where M 1 , M
2 as two adjacent points, sections E, M, M2E
2 is the result of sample point insertion, which is the interval E+ in FIG.
It is changed as follows: M 1M s M 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 using 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 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 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 above-mentioned steps 5tep14.15 and 5tep16.17, it becomes possible to delete and reinsert the points once inserted, and to 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, insert the outline (or section) through the VRAM 14 to the CRT 1.
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 P] in FIG. 112 is deleted, and FIG. 114 is an example in which sample point P] 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 P on the section from P D 1.2. In step 5, sample points to be deleted from K], K2, and P2 are determined. 5tep2 PD12
If the input is not a section instruction, it will be a one point deletion instruction,
At step 520, P input at step 52 is set as the sample point to be deleted. 5tep7, 5tep6 or 5
Delete the sample points determined in step 20 from Figure 1O (d), recreate the curve parameter table in (e),
Create display data and transfer it to CRT13 through VRAM14
Display above.

At 5tep9, accept the following input, and at 5tep10~
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 CRTI3 through the VRAM14 in 5tep16, and
p17 and turn off the deletion FLAG. Also 5tep1
If the judgment in step 5 is OFF, the state after sample point deletion is sent to the CRT 13 through the VRAM 14 in step 18.
, and turn on the deletion FLAG in step 19. The sample points once deleted in steps 16.17 and 18.19 can be restored and deleted again by simply 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 "Point Delete" menu using the PD12.At this time, if all sample points are not displayed on the character outline on the CRTlS 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 l points, pick the desired point using the right button on the PD12. To delete multiple points within a specified section, select 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 alpha head 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. E55.3 After picking fish E54, it is interpolated with a straight line (F'). Also, 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').

Megumi 1 and Returned Ball Next, the fish waste reversal 59-c in FIG. 4 will be explained using FIGS. 52 and 53. This function is called by selecting the "Fish waste reversal" menu.

Inversion is a function that inverts the attributes of the selected sample points, that is, changes the attributes of the selected sample points to intermediate points if there are endpoints, and change them to endpoints if there are intermediate points, and corrects the contour line.

The procedure for reversing fish debris 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. 1O(d) is changed. Figure 10(a),
The data in (b) and (d) are processed for display and stored in VRAM1.
4, the modified contour line is displayed on the CRTIS.

In the case of FIG. 52, M2 is changed to the end point, El, Ml,
M2, E2 are E,,M,,E3,E shown in FIG.
It becomes 2.

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 PDI2), set Pl to 5t
By inverting the point attributes again in ep 1, it is possible to return to the previous state. In this case, the 53rd
The state shown in the figure returns to FIG. 51.

Tachiho 1 Next, the point movement 59-d will be explained below using FIGS. 55, 56, and 57. To call this function, select [Move point j or "Move point vertically and horizontally" menu on 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, the button is not released after picking, the PD 12 is tracked as it is, and released 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 KBDIl, the same (K
Use the arrow keys on the BDII 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 end point, the attribute of the point adjacent to the selected point is 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 shown in flowchart 1 in Figure 60 and flowchart 56.
Settings are made using the editing screens shown in FIGS.

The movement flag indicating whether the sample point has been moved in 5 tepl is initially set to OFF. In step 5, pick one point P1 in the CR7 editing area. 5 step 3 and turn on the movement flag. In step 5, it is determined whether the above-mentioned adjacent points should also be moved. 5step5 is 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 normally 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 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.

5 step 6 accepts the next input, step
The received input is determined in steps 7 to 10. If the input is a menu pick as a result of the determination, this function is terminated. Also, if it was a normal point power, 5
At tepH, the input is performed manually at point P1, and the process from 5tep3 onward is repeated. If the input is any of the items shown in (1) to (3) above, in step 12, perform the steps shown in Figure 10 (
PI (x) and PL (y) in b) are changed, the display data is recreated, and is 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 movement, and turn off the movement flag in step 517.

If the determination at 5tep13 is OFF, the currently displayed outline shape is returned to the state after the sample point movement, and then the movement flag is turned ON at 5tep15. Set the movement flag to 0N10FF L, the contour data before movement,
By retaining the moving contour data in PMEM, 5tep14.15 and 5tep16.1
7, the return/removement of a point moved by -1 is PD12
You can undo just by operating the right button.

Warm-blooded. 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 X coordinate direction is displayed on the screen.

Point alignment is a function that moves the X coordinate or X coordinate of an arbitrary sample point to the same coordinate as the X coordinate or X 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, an X 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 X 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 on 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 is highlighted in black, and a line cursor, that is, a reference line, is displayed at the same X or Y coordinate as the reference point. Also, at this time, a crosshair cursor is displayed 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 the KBDII. 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 while the crosshair cursor is 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 in which the center button of the PD 12 has been changed to a line cursor in the X coordinate direction. In addition, at this time, PD
Press the middle button of 12 to return 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 E1 in (D). Place the crosshair cursor CC' on point E1, 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.

Figure 62 E. 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 F,...,M as the points we want to align.

Of course, it goes without saying that 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 based on the input from the PD 12, and a moving point chart (FIG. 643) is created. The moving point Chiful holds the moving point number (a
), the contour line No. of the moving point, L [il and the sample point N
Composed of MOVETAB consisting of o, P[il,

Execute p7 and later. If the input in 5tep6-1 is not a point pick, in 5tep6-3 it is regarded as the start of region designation, and the position of the PD 12 in 5tep6-1 is set as the coordinates of one point in the region. 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 Fig. 10(d).

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 this is set as PDATA'. Make P (x) or P (y) the same as the reference point, recreate the curve parameter table in (e), create the display data, and
It is displayed on the CRTla through A M l 4, and the movement flag is turned ON. FIG. 61(E) shows the state after the movement. At 5tep8, accept the next input, and at 5tep9~
In step 11, the receiver determines the input. As a result of the determination, if the input is a menu pick, this function is terminated. Also, if it is a normal point power, 5 steps
In step 12, that point is set as a reference point, and the process from step 3 onward is repeated. In addition, the input of 5tep8 is undo (PD12

The data of PDATA' held in EM6 is restored and displayed again, and the movement flag is turned off in step 15. If the movement flag is OFF, 5te at 5tep16
In step p7, the changed PDATA data, ie, the state after movement, is displayed, and in step 5, the movement flag is turned ON.

By setting the movement flag to 0N10FF, PMEM6
You can switch the display of PDATA and PDATA' on the top, and by doing so, the point moved once is retained as PDATA (after movement) and PDATA' (before movement) on PMEM6, and the current status is also displayed using the movement flag. By understanding this, it is possible to return the point that was once moved in steps 5tep 13.14 and 5tep 15.16, and to move it again by simply operating the right button on the PD 12.

1 Coarseness and Abundance I Method Next, 39-f contour line elimination in FIG. 4 will be explained using FIG. 67 (diagram 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 on PDI2. 5 step 3 and outline the 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. You can also use normal contour input (
(double click of a point on PD12), the input is set to L, and the process from step 3 onward is repeated. still,
5step5 input is und.

l.

The erase FLAG is determined in step 12, and if it is ON, the outline is displayed at 5 tep, and in 5 tep 12, the erase FLAG is turned OFF. Further, if the determination at 5 teplo is OFF, the contour line is erased at 5 tep 13, and the erasure FLAG is turned ON at 5 tep 14.

Through the above-described steps 5tep12 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.

Movement of the contour line will be explained using FIGS. 67, 68, and 69. The movement of the contour line is started by picking the "move contour line" menu on the PD 12.

Contour movement is a function that moves one or more character contours or specified sections in any direction or by any amount in either the X or Y directions. FIG. 67 shows the character data before movement. FIG. 68 is an example in which the two contour lines forming the character "D-1" 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 ( 88-1 in Figure 88 to finish inputting the contour line to be further moved at step 21.22.
88-2 is a table of menus for inputting each character information name and its value. In 5tep2, turn off the data input flag, and in 5tep3, wait for the input of the next data N.If the next data N is a menu pick in 5tep4, proceed to 5tep5, and if N is a value input menu, turn on the data flag. , return to step 3. If it is not a N or value input menu, turn off the data input flag (step 6), determine N in 5step 8, and if it is a No menu pick, return the newly set input value to the value before the start, and go to 5step 3. return. If it is a YES menu pick, check the currently input value and register the set value (5 tepH) Return to 5 step 3. 5 step 12. If N is the end menu or another menu in 5 step 13, the input value is checked in the same way as in 5 step 14, the set value is registered, and the process ends.

5 step 4 and if N is outside the menu pick, 5 step 15
If N is the key human power from KBDII, 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 5 step 18, and if the data flag is OFF, do nothing and return to 5 step 3, but if it is ON, echo the input value to the value input menu at 5 step + 9,
Perform the data input process and wait for the next data input in 5 steps. In other words, you can set the input value from KBDII using the value input menu only when the data input flag is ON, and then select 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.

iFu no Sara Yodo 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 in addition to 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. YES, NO.

Each end menu 90-1 and a table 90-2 of menus for inputting line names, positions, and display state switching are displayed.

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

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. It is displayed in the editing area and waits for the next input in 5 steps 3. At 5 steps 15 and 16, if N is the end menu or another menu pick, the currently input setting value is checked and registration is completed. 5tep
18 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 step 19, mainly process the input by KBDII, and end the input, and when using anything other than the return key at 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 521, input processing is performed, and the next data input is waited for 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 0N1
It becomes possible to refer to the 0FF menu.

= Data By selecting the main menu, the registration shown in Figure 93,
Move to the end screen. Step No. (Sn) shown below is as follows:
This is the number in FIG. 94.

First, a default menu is displayed (Sl).

If necessary, select an appropriate menu 93-1 with the PD 12 and change the line width information (32 to S3).

To register the data, pick 93-3 with PD12 and KB
The code can be changed by inputting it from the Dll (S6). Furthermore, by picking 93-4 with the PD 12, the correction work for that character can be invalidated (S7).

After registration, the next character to be called is the next code by default, but you can pick 93-6 with the PD12 and specify the code freely from KBDII (Sll). 93-7 to PD1
By picking 2, you can exit the registration end menu without calling the next code (S9).

Finally, it is executed by picking 93-8 with PD12. By picking 93-9 with PD12,
It is also possible to cancel the registration process (S13)
.

[Tube Surface Inspection] The tube surface inspection is started by picking the tube surface inspection menu shown in FIG. 8, and is performed by performing various operations on the basic screen shown in FIG. 95. FIG. 95 will be explained below.

95-1 is a font data file name list, which is a menu for specifying a font data file to be inspected. 95-2 is an area for displaying the font data file name selected in 95-1. 95-3
is an area for specifying the character code range to be displayed using PD12 and KBDII.

95-4 is an area for specifying the resolution of the output device as PD12 and KBDII. 95-5 is an area for specifying the display point size. Reference numeral 95-6 is a menu area for instructing the type of fill-in display, which will be described later.

Figure 96 shows the screen when the quality inspection shown in Figure 95-95-6 is selected. 96-1 is a data display area. 96-2 is a file name display area of the currently displayed font data selected at 95-1 in FIG. 96-3 is a menu group for controlling the display of the data display area 96-1. 96-4 is an area for displaying the resolution of the output device specified in FIG. 95-4.

埜>92且I In the case of a center inspection, only what is displayed in FIG. 96, 96-1, is for the center inspection, and 96-2 to 964 remain unchanged. Picking the menu 96-3 returns to FIG. 95.

The details of the quality inspection and center inspection are the same as the 85 printer output described later, so please refer to FIGS. 102 and 103 and the details of the printer output. However, the output device is different, and in the screen inspection, the display at step 9 in FIG. 103 is performed on the CRT 13 through the V RAM 14.

[Printer output] For printer output, use the printer output menu a-12 in Figure 8.
It is activated by picking , and various operations are performed on the basic screen shown in FIG. 97.

FIG. 97 will be explained below.

Reference numeral 97-10 is a menu for instructing scrolling (page break) of the font data file name list of 1 above.

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 Figure 97-97-3 and press any of A, B, C, or D in Figure 97-97-5.
This is done by picking at D12.

The contents of the display items A, B, C, and D 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 pig file is defined as 800 x 800 dots, it is displayed as 400 x 400 dots, which is used for a rough quality check, and B is the same as A. It is similar, but the inner outline is displayed as a dotted line, and C is a display in which one dot of data in the font data file corresponds to one dot on the printer, but at this time, a solid line is drawn between sample points. The outline 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. The display size of D, which is used to confirm the validity of the line width information, is the same as that of C, but the sample points are displayed with dotted lines and the contour lines are displayed 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 PMEM6. In 5tep2, the outline type selected in FIG. 97-5 is held in PMEM6. 5 Repeat the process from step 3 onwards. 5tep
3, the font data from the start code to the end code 1- held in the PMEM 6 in 5 tepl is read from the font data file of the DISK 3 and held in the PMEM 6 in the format shown in FIG. In 5tep4, it is determined whether the end coat has been output or there is no more data in the font data file, and the outline display process is ended. At step 5, the outline type held in PMEM 6 at step 2 is determined, and if it is C or D, scaling is applied to FIGS. 102 (a) and 102 (b) on PMEM 6 at step 6. In step 5, display data is created and stored in the PMEM 6 with reference to (b). 5 step 8
Judge the contour line type again, and if it is C, go to step 9.
Based on the data in FIGS. 102(b) and 102(C), a line segment representing the parent-child relationship of the line width information is generated and stored in the 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. 5te
For pH, the data created by 5 tep 7.5 tep 9.5 teplO and held in PM 6 is sent to 10, and the diagram shown in FIG. 98 is output from PRT 9.

Next, the filled display will be explained.

For filling display, specify the character coat range in Figure 97-3, enter the point size range in Figure 97-97, and pick the "Quality Inspection" or "Center Inspection" menu on the PD12. To do something.

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 PMEM6. 5
Repeat the processing for the specified 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. 5tep6 is 5te
The output type instructed in step p3 and held in the PMEM 6 is determined, and in the case of "center inspection", a pattern for inspection is created in step 5. The pattern is, for example, a normal character such as 0 or N, or a pattern such as a square, as shown in FIG. 99, center inspection. 5 step 8 then 5 step
4 to PMEM6 as shown in Figure 102 (retained FNTD
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 5 tepl, the start and end coats designated in FIG. 97-3 are held in PMEM6.

In 5tep2, the font data from the start code to the end code held in PMEM6 in the previous 5tep is read from the font data file of DISK3, and is held in PMEM6 in the format shown in FIG. 102. 5t
In ep3, 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 5tep4, Figure 102 (a
