Abstract

PURPOSE:To provide versatility in specifying a sampling point to be deleted by forming a graphic pattern corresponding to the sequence of existing sampling points based upon the attributes of sampling points adjacent to the sampling point to be deleted. CONSTITUTION:In figures, alphabets in parentheses indicate unexecuted states in respective cases and dashed alphabets in parentheses indicate executed states. Namely, when both the sides of a point to be deleted are straight lines (A), a straight line is interpolated (A') by deleting the point. When one side or both the sides of a point to be deleted is a curve, a new curve is interpolated (B') by deleting the point. When a point to be deleted is an intermediate point (C), a new curve is interpolated by a residual intermediate point (C'). Provided that, an intermediate point for a curve having only the intermediate point is deleted (D), a straight line is interpolated (D'). Consequently, versatility in specifying the point to be specified is provided.

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, it is usually necessary to create character sets (fonts) in units of typefaces.
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 JISX0208 "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, the graphic processing described above has the following problems. Conventionally, when considering point deletion as an example of graphic processing, there was no generality in specifying the points to be deleted, or the effect of deleted points on related patterns was not considered at all. There was a problem.

[Objective] In view of the above points, an object of the present invention is to provide a graphic processing method that provides versatility in specifying points to be deleted.

In view of the above points, an object of the present invention is to provide a graphic processing method that takes into consideration the influence of patterns related to points when they are deleted.

[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 the IR7, expressed using 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 mean the point itself, and sometimes mean a point attribute that is a property 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.

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 the PMEM 6. FIG. 10(a) is an area that holds the number of contour lines n1oop constituting a character pattern. Figure 10(b) shows the number of sample points n constituting each contour line.
10(d) shows an array of areas that hold the address addrl of the sample point information storage area in 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 X%Y%
Detailed point attributes and if the sample point is the starting point of the curve,
This is the address of the area for storing the attributes of the curve, that is, the array shown in FIG. 10(e). FIG. 10(e) shows the attributes of the curve, in this case, taking a cubic B-spline as an example, the number of coefficient sets ncoef and the coefficient a 11 ) for determining the curve.

becomes. (b) is an array of sizes equal to the number of contour lines, so in the case of levers, there is an array of size 2, each 1.7 (L
O), 13 (Ll).

In the sample point information storage area (d), P[0] is an end point and is not the starting point of the curve, so PDATA[0]
] has a point attribute value of 0. Since P[1] is the end point and the starting point of the curve, the point attribute value of PDATA[1] is the number of sample points constituting the curve, 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]

Correcting operations such as point deletion and point movement performed by the operator using the PD 12 are realized by making changes with reference to FIGS. 10(a), (b), (d), and (e).

The display changes on the CRT 13 are shown in Figures 10 (a), (b), and C.
d), (e), etc., by converting it into human map data and transferring it to the VRAM 14.

[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, coat setting, center setting, noise removal, contour line generation, and so on.

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

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

A font coat 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.

manag for each user to manage the progress of Deciquiz
efile is prepared. The managefile is a matrix of number of pages x number of characters, and a completed step flag is set for each character of each pen. For completed steps, the menu field will be reversed and turned black, making it impossible to pick. If you pick b-5 with PD12, you will get the 15th
Moving to the figure, by picking any page number and selecting YES, you can save the managefile of that page.
You can initialize the flag and cancel the Deciquiz for 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 Deciquiz for one page is completed from scanning to outline generation, the mana of that page is
The flag of gefile is initialized, and all the menu fields of that page in b-3 are reversed and become white, allowing them to 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, it is possible to read this during scanning, automatically recognize the distortion of the document and the scan direction, and perform appropriate processing. be. FIG. 16 shows an example of a manuscript.

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 flowchart 1 in FIG. 18. Select the menu with PDI2, and if it is b-9, end (step). If there are scans 1 to 5, IR7 is activated, and the image data of each character on one page of the original is transferred to PMEM6 in a preset order.
The data is stored in DISK 3 (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, you can rescan by selecting b-7 using D12 (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 DISKa is also deleted (step 6).

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

From code setting Figure 14 b-3, select the appropriate page menu of court settings 1 to 5 using 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 column is in the code setting style (step 3), the number of set characters is decreased by l (step 4). When the coat is input from KBDll (step 5), it is set (step 5).
p7) The character corresponding to the character code is displayed in the corresponding column of bll (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, you can 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 pickable page number is
Court settings must be completed.

The center setting procedure will be explained using the flowchart of FIG. 22. First, use the PD12 to pink 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 crosshair cursor (step 3), and the center can be set.

Place the cursor on the center mark marked on the manuscript board in advance and click the left button of the PD12 (s
step 4), the body frame will appear 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 then pick it up (step 6) and input it from KBDII to change it (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 a suitable vane menu for 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 nostle 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 the corresponding image data stored on the PMEM 6. Note that the description here assumes that the necessary part on the image data, that is, the part representing the character, is the corresponding hit month (on) in the memory.

The present invention introduces the concept of a body frame, and has a function to delete all people outside the body frame and 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 using the PD 12 and switching between 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, the noise removal for that character ends (5tepH), and the image data is displayed on the DISKS.
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
The process updates le and ends the process (step 2).

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

・Outline generation-3 starts automatically by picking a suitable vane menu from 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. This value can be changed manually from KBDJI by picking b-18 (step
2). In addition, parameters for feature point extraction and sample point automatic generation when automatically generating font pigs 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. Each parameter corresponding to the typeface is stored in, for example, PMEM6.

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 D I S K 3. 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, yj) from the reference point of the image data. The method of extracting the contour point sequence is realized by using the method proposed by the present applicant in Japanese Patent Application Laid-Open No. 6/1-71767, or by using 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 part, as shown by - (square) 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 outline generation is completed for all characters (step 5), the manager is automatically initialized and terminated (step 6).

[Character Production] Character production is performed by performing various operations on the basic screen shown in FIG. 30. It goes without saying that the explanation here is written in letters or is not limited to letters. The basic screen has, for example, 1280x1024 pixels and is composed 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-1 to A-1) 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 coat 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 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.

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 saving such as return, save at -time, and registration/end.

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 39-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 PMEM6, if necessary, ]]S
It inputs data from K3, changes and processes data already on PMEM6, transfers the data to VRAM14, and displays it on CRT13.

undo-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.
This is the input to execute the dO-redO operation, and is the und that should be performed in each processing procedure.

and redo (undo of undo), or by providing a menu for undo-redo, which will be described later, and when selecting the menu, undo/redo is executed for the immediately previous change in graphic data.

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

10 is a flowchart showing an example of 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 Fl. 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 the N is an operation that instructs to change the figure data Fi, for example, to delete each vertex of figure Fi, in 5step 7, the figure If Fi is not stored in the undo table, F
For i, 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 and display the result. 5t
eplo) and waits for input of the next data N (step 3).

If Fi 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 2), 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 step 5, in the process of step 1, all figures F1 in the undo table will be exchanged again, so redo will be performed, and step 11
~+-2 means that undo/redo is repeated.

Interrupt Menu Control Interrupt menu control will be explained. An interrupt menu is a menu that can be executed during each operation of 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 and receives input from the operator at 5 tepl (Nl)
, If Nl 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 allows you to exit each menu without giving an instruction to exit.

The input control section will be explained in (b). Receive input information from the operator in 5 tepl and set it to Nl, 5 tep
In step 2, Nl is determined, and if Nl is not an interrupt menu, N1 is output and the process ends. When N1 is an interrupt menu, each interrupt menu process is performed 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 creation S3, where 33-1 is a part having each function of character data correction in S9 in FIG. Part with each function of display control of S8 in the figure, 33-3
33-1 is a part for changing font data, 33-4 is a part for changing display data, and 33-1 to 33-4 are parts for changing font data.
is on PMEM6, and 33-a is on 33-
If the font data actually changes in 1, 3
3-3 means requesting font data change,
Similarly, 33-b also changes display data etc. from 33-2.
-4, 33-c indicates a request to 33-4 to change the display due to font data change, and 33-d indicates that 33-4 is actually 1mCRT131. mV
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 33-0 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
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 the data is, display magnification rate S1, display reference point coordinates O, 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 developed in the display coordinate system, original display data 1, and line display data 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,
Deploy the human map 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. 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. Curve division interval N at 5tep3
Enter. In step 4, the font data previously stored on the PMEM 6 is converted into coordinates using S and O, 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. 10(e), and the curved portion of N are developed into a vector. 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).

Now, let me explain about Figure 35 ((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-1(X), P of the sample point in FIG. 10(d).

(y) is a value that has been coordinate transformed for display, and for fish debris, L means the line start point and C means the curve start point, and in the case of C, the curved part was expanded into a short vector. The address of area (d) is shown (.(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 DT=3, font display data is input, when DT2, 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, DDATA sample point display . That is, when displaying a curve, in (C), when the point attribute is C, addr2 is referred to, and the data connected by line segments including the short vector data in (d) are used as display data. When displaying a straight line, the data of (c) only,
Display data is data in which only sample point coordinate data is connected in order.

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 5tepl 1, input the flag PF indicating whether to fill in the outline of the display data selected in 5step 8.9 and the display data created in 5teplo. PF = 0 indicates the outline, PF = 1 indicates to fill. be. 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 step 513, if the VRAM can have multiple 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
The data is developed into a bitmap on the VRAM 14 according to TXDF, WD, PL, and DS, 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, 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 1 with l (. 5 step 2 and enter the display destination area WD'. If you want to scroll the editing area, press W
D' Edit area. PD the reference point O' in 5tep3
Input from ll. 5 step 4 display processing) Input and null values N01DTSST, PF, WD.

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) and stored on PMEM, the current values are substituted for DT and 5TXPFSPi, WD' of 5tep2 is substituted for WD, and the display flag DS
Assign erasure to , and in step 5, erase the display using the display process described above. 5tep6 is a part for determining whether to repeat 5tep4.5 for all data types (n). If there is still data in the display state, 5tep7 is incremented by 1, and 5tep4.5 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.
, and for S and H, the current values for display data number No. are substituted.

In 5step9, create display data according to the display data creation procedure described above, set 1==0 in 5teplo,
5tepl In step 1, input values necessary for display processing are set. For DT, ST, PF, and PL, the current display state corresponding to No. is substituted, and for WD, the display is substituted for WD' and DS input in step 2.

In step 12, display is performed according to the display process described above,
5 step 13 to update the current display state P M E M
Repeat this process for the data to be displayed, and then finish.

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, 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 W D' is input. If the editing area is zoomed, the editing area is assigned to WD'.

5 step 2, turn the shape of the tsuru into a long cross.
Change to vine. The cursor will be explained in 5 steps below.
3 to display the display center. 5 Step 4 waits for input from the operator. 5 if input Nd or other menu pick
At step 17, end processing is performed and the process ends. The termination processing includes processing such as returning the cursor shape to its original shape and not displaying the center. When the first iris P1 of the rectangle is input at 5tep6, the input of the point P2 of the next rectangle is waited for at 5tep8.

If the input Nd is another menu in step 9, after the termination process,
When the process is finished and there is an undo instruction (step), cancel Pl (5tepH) and return to 5step4. s t
When rectangle 2nd fish P2 is specified in e p 1.2,
For example, when the vertical and horizontal lengths of a rectangle with PI and P2 as two diagonal points are calculated, and the vertical and horizontal lengths of the area specified by w and WD' are H and W, the magnification rate S' = m i n (H/h, W
/w) Center ○' - Make it the center of the 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 Regarding the input of Nd, for example, a left button click is an input of Pl, and a middle button click is an input of an enlargement ratio. 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 given by Pl and P2.

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

”! Hong 4th Explain standard sizes.

Standard size is a function that does not return the scrolled or zoomed display state to the original size and display position. The original display state is, for example, the font data], d
This refers to displaying so that a t corresponds to one pixel in the display area and 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. , 0 as the initial reference point O8 and the area WD' as new inputs.

Original ON/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.
L.

Also in the display processing unit (b), No←F(WD'
) WD' can be realized 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 in a different brain from the font display data and can be viewed overlappingly.

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

This menu is also a toggle menu. Display processing section (b
), N○←F (WD'), DT←1, ST←
Just enter 3.

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

・This menu is also a toggle menu. Similarly No4-
F(WD'), PF+-ON, and display processing is performed by switching DS←display/erase every 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.

Line ON/OFF lines, for example auxiliary lines, 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.
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 Ca) in Figure 46 and the short crosshair cursor shown in (b). When ON, the long crosshair cursor is displayed, and when OFF, the short crosshair cursor is displayed. do. This display can be controlled, for example, by changing the general cursor, or by having cursor data as display data and displaying it using the same processing method as display processing (b), as shown in the display control above. This can be achieved by

4 display FIG. 4 82-10 Redisplay 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 explaining the redisplay operation, and in each input waiting state (step) during character creation, when instructions are given by PD]2 and KBDll (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 in 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.

Point 11 Next, insertion of point 39-a in FIG. 4 will be explained using FIGS. 18 and 49.

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.

Fig. 48 shows the state before point insertion, and if Ml and M2 are specified as two adjacent points, the sections E, M, M2E2 are as follows.
As a result of sample point insertion, sections E, M, and M3M in Figure 49
2E2.

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 that inserts 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 flowchart 1 in FIG.

After inserting a point at 5 tepl, Kaka's flag "insert FLAG"
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 4, the point attribute of the insertion point is determined from the point attributes of PI and P2 according to the above-mentioned fish waste determination rule. After recalculating the curve noclameter etc. of the section affected by the point insertion and displaying it on the CRT 13 through the VRAM 14, the insertion FLAG is turned ON in step 5.

In step 5tep6, the next input is accepted, and in steps 7 to 10, the received 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 strength, the input is set as the first point input at 5 tep, and the processing from 5 tep 3 onward is repeated. In addition, if it is a movement instruction (KBDIII arrow key), move the point inserted in 5tep12 and transfer it to CRT13 through V RAM 14.
Display the changed outline above and return to 5step6. still,
If the input in 5step 6 is undo (right button on PD12), check the insertion FLAG in 5step 13, and if it is ON, return to the outline display before inserting the sample point in 5step 4. Delete the inserted sample points, redisplay the contour line), and turn off the insertion flag in step 17. Further, if the determination in step 3 is OFF, in step 5 step 14 the point is reinserted to display the state of the contour line after point insertion, and the contour line is redisplayed), and in step 15 the insertion flag is turned ON.

Through the steps 5tep14.15 and 5tep16.17, it is possible to delete and reinsert the point where the foot has been inserted, and to redisplay the outline by simply 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 V RA Ml 4.
Display on RT13.

Next, using FIG. 112, point deletion S! 11-b will be explained below. Point deletion is started by picking the "point deletion" menu on the PD 12.

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 the sample point PI in FIG. 112 is deleted, and FIG. 114 is an example in which the sample point PI 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, it is determined whether the input to PD12 at 5tep2 was a section instruction (pressing the middle button), and if it is a section instruction, the point P is regarded as the section end point Kl, and 5tep4゜5tep
5, input 2 to the end point of the section and point P2 on the section from PDI2. In step 5, sample points to be deleted from K1, K2, and P2 are determined. If the input of PD12 at 5tep2 is not a section instruction, it is designated as a deletion instruction for 1 point, and the input at 5tep2 is
At p20, P input at step 5 is set as the sample point to be deleted. 5tep7, 5tep6 or 5tep
The sample points determined in step 20 are deleted from FIG. 10(d), the curve parameter table shown in FIG.

At 5step9, accept the following input, and at 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

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 can be restored and deleted again by simply operating the right button on the PD 12. (For example, the display of FIG. 112 can be switched from that of FIG. 113 to that of FIG. 113 simply by operating the right button.

) Point deletion 59-b will be explained below using FIG. 51. Reading of this function is performed by picking the "Point Delete" menu with the PD12. At this time, if all sample points are not displayed on the character outline on the CRT 13 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 section. To delete one point, pick the desired point with the left button of PDI2. 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 P D 1.2. FIG. 51 is a diagram showing an actual example of point deletion, and the alpha head in parentheses and the dashed alphabet 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 deleting points, a new curve is interpolated using 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 and the iris E63 in (G), interpolation is performed using a curve (G').

Next, the point attribute reversals 89-C in FIG. 4 will be explained below using FIGS. 52 and 53. This function is called by selecting the "Invert Point Attributes" menu.

Point attribute inversion is a function that inverts the attributes of the selected sample points, that is, if there is an endpoint, it is changed to a midpoint, and if there is a midpoint, it is changed to an endpoint, and the contour line is corrected.

The procedure for inverting point attributes is shown in the flowchart in Figure 54 and in Figure 5.
This will be explained using the editing screen of Section 2 and FIG. 53.

At 5 tepl, select one point in the CRT editing area, for example, Pl.
Pick (M2). At 5 step 2, P M E M
10(b), the end points and intermediate points are inverted, and the parameter table showing the curve in FIG. 10(d) is changed. The data in FIGS. 10(a), (b), and (d) are processed for display, and V
The modified outline is displayed on the CRT]3 through RAM 1.4. In the case of Fig. 52, M2 is changed to the end point, and El, Ml, M2, E2 are changed to El, M shown in Fig. 53.
It becomes l, E3, E2.

5Step 3 Accepts the next input, then steps
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, the input is set as PI in 5step7 and
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.

Lazy vine 1 Next, the point movement 59-d will be explained below using FIGS. 55, 56, and 57. To call this function, select the "Move point" 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 up/down/left/right in increments. However, if allokey movements are performed continuously, the amount of movement 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 the state in which the picked point N・1' is being moved by track by PD]2, and the new
The line segment is displayed as a dotted line in real time as the point M' moves. Next, (C) shows a state where 1'' is fixed at the moved point 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 at 5tcpl is initially set to OFF. 5 step 2, pick one point Pi in the CRT 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 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.

At 5tep6, the next input is accepted, and at 5tep7~10
If the input is a menu pick, the 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 one of the items shown in (]) to (3) above, in step 512, P in FIG.
I (x) and PI (y) are changed, display data is recreated, and displayed on the CRT 13 through the VRAM 14. If the input is undo (right button on PD12), the movement flag is determined in step 1.3, and if it is ON, the currently displayed The outline shape is returned to the state before the sample point movement, and the movement flag is turned OFF 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. By setting the movement flag to 0N10FF L and holding the contour data before movement and the contour data being moved in PMEM, 5tep14.15 and 5tep16.
17, the return/re-movement of the point that moved once is PD1
Undo is possible by simply operating the right button of 2.

Point n 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, the X coordinate alignment or the X 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. Change the display and go. Furthermore, the same (
The XX coordinates of the line cursor can be switched using the middle button of [PD]2. Next, with the line cursor displayed on the screen, a reference point is selected by picking an arbitrary sample point using the left button of PD]2. The selected reference point is displayed in black (inverted), and a line cursor, that is, a reference line, is displayed at the same X coordinate or X coordinate as the reference point. Also, at this time, a crosshair cursor is displayed separately from the reference line. .The position of the reference point (reference line) can be corrected in dot units using the arrow keys on KBDII.Next, select the sample points you want to align other than the reference point.The selection method is to align the points one by one. There are two methods: picking a rectangle, and specifying a rectangle and targeting 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 X coordinate direction is displayed on the screen.

(B) shows a screen in which the center button of PDI2 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 a line cursor in the X coordinate direction is displayed and the reference point EO is picked with the left button of the PD 12. At this time, the line cursor is fixed as a reference line to the X 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) does not show the 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 designation.

Figure 62 E. is the reference point, l is the indicated rectangle, E,
, Nq , Lt sample points included in rectangle 1, 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 goes without saying that you can add or cancel target sample points both inside and 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 step 2, select one point in the CRT editing area, for example E. Input the coordinates of from the PD12. In step 5, a vertical line or a horizontal line is generated as a reference line from the coordinates input in step 5 according to the vertical and horizontal directions of the cursor, and is displayed on the CRTla through VRAMI4. In 5tep4, KEDII
Enter the amount of movement indicated by the arrow keys above. 5te
In step 5, change P (x) and P (y) in Figure 1O (d) based on the amount of movement of the Eo1 reference line input in step 4, recreate the curve parameter table in (e), and change the display data. Create a CRT1 through V RAM 1.4
3 Display on top. 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. 643 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'l], and exists on PMEM. 5tep6 will be explained in detail using the flowchart of FIG. 64-2. 5
At step 6-1, data from the PD 12 is input. 5
In step 6-2, it is determined whether the input is a point pick (left button). If it is a point pick, 5tep6
-12, move the picked sample point
Register. 5 step 6-13 accepts the next input,
5tep6-14. In 6-15, the accepted input is determined. As a result of the judgment, if the input is a point pick, 5t
Repeat the process from ep6-12 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 step 6-1 is not accurate, it is regarded as the start of region designation at step 6-3, and the position of the PD 12 at step 6-] is set as the coordinates of one point in the region. Similarly, in step 56-4, the position of PDI2 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
(x), P (y) and search, MOVETAB
Register. At step 56-6, the next input is accepted, and at step 67.6-8, the accepted input is determined. As a result of the judgment, if the input is a point pick, 5 steps
In 6-9, it is determined whether the picked point is registered in MOVETAB, and if it is registered, 5

If the input at 6-6 is an execution instruction (middle button of 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. In addition, if it is a normal point strength, the point is set as a reference point in 5tep+2, and the process from 5tep3 onward is repeated. In addition, 5t
If the input for ep8 is undo (right button on PD12), determine the movement flag in 5step13,
If it is ON, return to the state before moving the point in 5tep14, that is, the data of PDATA' held in PMEM6 in 5tep7, and redisplay it, and then repeat the display in 5tep14.
15, the movement flag is turned OFF. Movement flag is OFF
If so, in 5tep16, the data of PDATA changed in 5tep7, that is, the state after the movement is displayed, and in 5tep17, the movement flag is turned ON.

By setting the movement flag to 0N10FF, PMEM6
It is possible to switch the display of PDATA and PDATA' above, and by this, the point moved once is retained as PDATA' (after movement) and PDATA' (before movement) on PMEM6, and the movement flag is used to display the current point. Once you know the state, you can return the point that was moved in steps 5tep 13.14 and 5tep 15.16, or move it again just by operating the right button on the PD 12.

Next, 39-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 using the PD12.

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. s t e p: 3 erases the outline from the CRT 13 through the VRAM 14, and 5 te
Turn on the erase FLAG at p4. 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. In addition, if it is a normal contour manual input (double-clicking a point on the PD 12), the input is set to L and the processing from step 3 onward is repeated. In addition, the input of 5tep5 is und.

l.

If it is ON, display the outline at 5 tepl 1, and then erase it at 5 tep.
At step 12, the erase FLAG is turned OFF. Also, 5 tepl
If the determination at O is OFF, the outline is erased in step 5 13, and the erasure FLAG is turned ON in step 5 14.

Through the steps 5tepH, 12 and 5step13.14, it becomes 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 one wheel's moving contour will be explained using FIG. 67, FIG. 68, and FIG. 69. Contour movement is activated by picking the ``contour movement'' menu in P D 1.2.

Contour movement is a function that moves one or more character contours or a specified section by an arbitrary amount in an arbitrary direction or in any 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. Initialize [movement FLAGj], which is a flag indicating whether the contour line or section has been moved, to OFF in 5 tepl. Input the first point from PD12 in step 5. In 5tep3, it is determined whether the input of P D 1.2 in 5tep2 was a contour line instruction (double click), and if it is a contour line instruction, in 5tep21.22,
Furthermore, the input of the contour line to be moved is continued until the end is instructed. In step 3, if there is no outline instruction,
Regard Pl input in 5tep2 as the end point of the section, and
At p4, the other section end point is input from PD12. 5
In step 5, points on the section are input, and in step 6, the moving section is determined.

At 5tep7, accept the next input, and at 5tep8~11
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 power, the input is set as the first point input - in 5tep12, and the processing from 5tep3 onwards is repeated. In addition, if the movement amount or movement direction is specified using the arrow keys or numeric keypad 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 14, and transferred to the CRT 13 via the VRAM 14. Display data. 5tep
Turn on the movement FLAG at step 15.

In addition, if the input of 5tep7 is undo (right button of PD12) (judgment 5tepH), 5tep1
In step 6, determine the movement FLAG, and if it is ON, in step 17, change the state of the contour line or section before movement to V.
Display on CRT13 through RAMI4, 5tep18
to turn off the movement FLAG. In addition, if the determination of 5tcp+6 is OFF, the state of the contour line or section after movement is transmitted to the CRT1 through the VRAM14 in 5tep19.
3 and turn on the movement FLAG in step 20. By the above 5 step 17.18 and 5 step 19.20, the contour line and section that were once moved are returned and re-moved.
This can be done by simply operating the right button on the D12.

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

Randan Yutaka 11 Next, virtual line generation 39-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 contour line created with this function can be modified in the same way as normal contour lines in other functions, such as point insertion, point movement, etc.
It can be changed to any shape. The difference between virtual lines and character outlines is that virtual lines are mainly used for character creation work, and are not recognized as character outlines. It is not stored.

The main purpose of using virtual lines is to use them as templates (underlays) when editing contour data, etc., and to create curved parts that appear continuous, such as sections E1 to E2 and sections E3 to E4 in Figures 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, initialize the flag "display FLAGJ" indicating whether an arcuate figure is displayed to OFF. At 5 tep 2, input the coordinates of one point, for example 11, in the CRT editing area using PDI 2. Next, at 5 tep 3, for example, Input the coordinates in the same way. 5step 4 calculates the outline data (sample point coordinates) of the arcuate figure Yl from the coordinate values of rl and 12. The outline '1 is the end point E1, E2 as shown in Fig. 74. , intermediate points M1 and M2, and the coordinate values of these sample points are calculated as follows.

E1x=Ilx E1y=11y E2x-12x E2y=12y M 1 x = I 1 x ten (I 2 x - I
1 x ) * KM1y=11y M 2 x = I 2 x M2y=12y-(I2y-fly)* where K is a constant held in the program memory 6, and in the case of FIG. It is 55. The contour line data Y1 calculated in this way is converted to V RAM in step 5.
After displaying on the CTR13 through step 14, the display FLAG is turned on at step 6. In step 5, the next input is received, and in steps 8 to 1, the received input is judged. 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 made the first iris input in 5tep12, and the processing from 5tep2 onward is repeated. Also, if it is a reverse instruction (middle button on PD12), 5te

If it is (upper right button), (judgment 5tepH),
In step 5 step 16, the display FLAG is determined and it is ON.
If so, the currently displayed arcuate figure Y1 is erased in 5tep19, and the display FLAG is erased in 5tep20.
Turn off. In addition, if the determination at 5tep16 is OFF, after displaying the sample point data of the arcuate figure Y1 at 5tep17, the display FLA is displayed at 5tep18.
Turn on G. 5tep17.18 and 5tep above
19.20, it becomes possible to erase or redisplay the arcuate figure that has been created just by operating the right button on the PDI2.

Next, the regular arc 89-1 in FIG. 4 will be explained using FIG. 75.

This function is called by picking the "regular arc" menu on the CRTIa. This function is for CRT1
The present invention provides a means for easily changing the shape of the curved portion of the contour line displayed on the 30 editing area to a circular arc or an elliptical arc. Here, for curved parts such as circular arcs and elliptical arcs, this device performs B-3pline approximation, and automatically generates control points for this, 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 P1 of the sample point on the figure. Next 5 step 3
Input the adjacent end point P2 on the same contour line. Pi, P2
In step 5, sample points are calculated to generate a new elliptical arc for the curve in that section. When the coordinates of Pl are (Elx, Ely) and P2 are (E2x, E2y), the method for calculating the intermediate point is shown below.

Intermediate points Ml and M2 are generated as shown in FIG. 76 by the X coordinate of the end point E1 and the X coordinate of the end point E2, and the interval El-PI
It is replaced with the sample point between ~E2.

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

M 1 x = E l x 10 (E 2 x −E
l x )・K or ElxMIy=E1y or E 2
y + (E 1 y −E 2 y )・KM 2
x = E2x or E1x+ (E2x-Elx)
・KM 2 y = E 2 y + (E 1 y
−E 2 y )·K or E2V Here, 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
In step 6, the next data N is accepted, and in steps 7 to 10, the determination is made and if N is a menu pick, the process ends. Furthermore, if N is the input of the end point Pi, return to 5tep3. If N is an instruction to change the unevenness, calculate the sample point at which the unevenness has been changed in 5tep13, set the figure as C2, delete 01 in 5tep14, and then change C1 to C2 in 5tep15. Next, set L to 2 if it is for uneven flags, and set L if it is 2 (step 1
6), return to step 5 and display C1.

When N is an undo instruction, C1 is deleted and the original figure is restored (step 12). Then, the process returns to step 5 and accepts 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 selecting the "Graphics" 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 generate control points of about 15 plines, which 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 PD,
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 of the regular polygon, for example C1, and the number of angles is input after determining the regular circle.

2 circles, 2 lines, 1 Next, regarding the center movement to 39- in Figure 4, see No. 80.
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 state where the cursor display is OFF is displayed on the CRT 13 through the VRAM 14. 5te
In p13, from the character information on PMEM, the body frame,
Display the baseline in the same way as 5tep2. At this stage, the editing screen appears as shown in FIG. 80. KB in 5tep4
Input data for movement direction instruction using the arrow keys on the DII. In step 5, based on the data input in step 4, the body frame and the pace line 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 outline as part of the process, so this is not a problem. Furthermore, in step 5, the amount of movement is held in PMEM.

5tep6 accepts the next input, 5tep7~IO
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. Also, if the input is the return key on KBDII, 5tepH and 5t as described above.
The sample point coordinates of all outlines are changed as follows from the movement amounts dx and dy held in PMEM in ep5.

Px [i] 2Px [j3-dx Py [i] =Py [j] -dy The contour data changed in this way, the body frame and baseline before moving in step 5 are as shown in Fig. 82 < VRAM14 After displaying on CRT13 through 5 step 12, move F
Turn on LAG and return to step 5.

In addition, if the input of 5step6 is undo (right button on PD12) (steplO), 5step1

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
Step 15: Turn on the movement FLAG. 5 steps above
14.15 and 16.17, it becomes possible to restore/move the contour data once moved by simply operating the right button on the PD 12.

The necessary undo/redo menu is the undo-red mentioned above.
.

The process is provided as a menu and its function is displayed. For example, when this menu is picked, such as one other menu Pick of the end process of step 6 in FIG. 31, steps 11 to 12 of FIG. 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.

5tepl T: 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.

5step 5 If N is the pick of menu 5, 5te
At p6, switch the current coordinate system to absolute coordinates-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 the point number, blinking property, X coordinate, and y coordinate in this order. If all sample points cannot be displayed in this area at once, refer to the next page 7 using the scroll menu. N input is 5tep9
If you pick menu 2, scroll Table 1 (step 10). Display the previous item ↑, display the next item ↓
This is an expression. 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 eco of the next coordinate will be displayed in the 4th column starting from the top. When the 4th column is displayed, the eco of the next coordinate will be set to 4th, and the coordinate value that was in 4th will be changed to 3rd and so on. Scroll (,
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 coordinates in real time, and when it is ON, area 86-
7, the coordinate values when dragging the sample point are displayed in real time.

Kazushi Noni IJL Jo 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.

Character information does not include font data such as the coordinates of sample points that make up a character and its character, but rather information such as the height and width of a character, rather than values that are common to the typeface. It refers to information related to the coordinate system of a character, which has a unique value for each character.

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 flowcharts 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 steps (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 N.
If is a value input menu, turn on the data flag and 5
Return to step3. When N is not in the 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
Check the input value in the same way as H, 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 5 step 18, and if the data flag is OFF, do nothing and return to 5 step 3, but if it is ON, go to 5 step 19, echo the input value in the value input menu, perform data input processing, and input the next data. Wait for 5 step 3, that is, enter value input menu K B I) I]
The input value from can be set when the data input flag is O.
It is only visible when N is selected, and after 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.

iFuno Sign 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 D for each operator.
It is registered in ISK 3, and unless the settings are changed or deleted, it can be loaded onto PMEM 6 and referenced as needed.

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. ＼You will be able to collect items such as lances.

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-L and a-e in the symbol field correspond to lines AxL and a-e in the editing area, A-L is used for setting a horizontal line, and a-e is used for setting one vertical line. do. In other words, the values entered in the position input menu field are the y coordinate value for A-L, and the y-coordinate value for A-L,
For , enter the X coordinate value. The display state switching menu field is a menu for switching the display flag for each line to display or hide the set line. When it is displayed, the line is displayed in the editor 11a. do.

At 5 tepl, lines are displayed in the editing area only if the set display flag for each line is ON or ON according to the current setting state.

The font data file name list of 97-1 is created by searching for rlsK3 when starting printer output.

First, outline display will be explained.

The outline is displayed by specifying the character code range in 97-3 of FIG. 97 and picking any one of A, B, C, D in FIG. 97-5 with the PD 12.

The contents of the display items A, B, C, and D are shown below. That is, A
is the coordinate value of 1/2 of the pig in the font data file, that is, for example, if the data in the font data file is defined as 800 x 800 dots,
400 x 400 dots are displayed, and are used for rough quality checks. B is the same as A, or the inner outline is displayed as a dotted line, and C is one dot of data in the font data file. It is displayed in correspondence with one dot of the printer, but at this time, the lines between sample points are displayed as solid lines, the contour lines are displayed as dotted lines, and in addition, well-known lines are used to prevent quality deterioration at specific character sizes. It displays the width information along with its parent-child relationship, and is used to detect a one-dot shift in sample points and confirm the validity of the line width information.D is the same display size as C, but , the sample points are shown with dotted lines, and the contour lines are shown with solid lines.

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

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. As shown in FIG. 111, compression is performed by first rearranging the data in state A in code order so that there is no gap, and putting it in 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 expandability 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.
