Abstract

PURPOSE:To speedily and easily generate a bit map font of high quality by selecting a contour correcting means or bit map correcting means according to the correction quantity of the generated bit map font. CONSTITUTION:A correction selecting means 10 selects the contour correcting means (keyboard 12 and mouse 13) for the rough correction of a bit mpa font which is, for example, large in correction quantity or the bit map correcting means (mouse 13 and a cursor) for the finish correction of a final bit map which is small in correction quantity according to the correction quantity of the bit map font that a user specifies. Thus, those correcting means are properly selected to correct and edit outline data and a bit map pattern. Consequently, the bit map font of high quality can speedily and easily be generated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a font creation device that creates a desired bitmap font from pre-stored outline information of characters and figures.

[Conventional technology]

Conventionally, in this type of device, when creating a bitmap font desired by a user, predetermined contour information stored in a disk or the like is read out and modified/edited, and the modified/edited contour information is read out and modified/edited. In one case, a desired bitmap pattern is developed according to information to create a bitmap font for characters and figures, and in the other, a bitmap pattern is developed according to predetermined contour information stored in a disk or the like in advance. In some cases, bitmap fonts of desired characters and figures are created by modifying and editing the developed pitmap pattern.

[Problem to be solved by the invention]

However, in the above font creation device, the correction/editing of the outline information and the correction/editing of the bitmap pattern are performed as separate operation procedures, so for example, when re-correcting a pattern that has been corrected/edited, To,
If the outline information is corrected or edited even though the amount of correction is small, the bitmap pattern must be developed again after that, so there is a problem that it takes time to create a bitmap font. If you modify or edit a bitmap pattern even though the amount of modification is large, 1
Since the correction/editing is done dot by dot, there are problems in that it takes time to correct/edit and create bitmap fonts.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a font creation device that can quickly and easily create high-quality bitmap fonts.

[Means to solve the problem]

In the present invention, contour information constituting the contours of character and graphic patterns is stored in advance on a disk, etc., and a desired bitmap pattern is developed in a real memory, etc. according to the contour information, and bitmap patterns of characters and figures are mapped. A font creation device that creates a font includes outline modification means such as a keyboard or mouse that modifies the outline information, bitmap modification means such as a keyboard or mouse that modifies the developed bitmap pattern, and A correction selection means such as a central processing unit (CPU) is provided for selecting either the outline correction means or the bitmap correction means according to the amount of correction of the bitmap font.

[Effect]

The correction selection means selects a bitmap font according to the amount of correction specified by the user, for example, the outline correction means performs rough corrections on bitmap fonts that require a large amount of correction, and performs final corrections on final bitmap fonts that require a small amount of correction. This is done using a bitmap modification method.

Therefore, by appropriately selecting each modification means to modify and edit outline data and bitmap patterns, it is possible to quickly and easily modify high-quality bitmap fonts.

〔Example〕

Embodiments of the present invention will be described in detail based on the drawings of FIGS. 1 to 4.

FIG. 1 is a block diagram showing a schematic configuration of a font creation device according to the present invention. In the figure, a keyboard/mouse control unit 11 receives contour information (hereinafter referred to as "outline data") according to the present invention from a keyboard 12 and a mouse 13 connected to the keyboard 12 and data for modifying a bitmap pattern. Various data and commands, including information and commands, are controlled manually. Central processing unit 10
(hereinafter referred to as rCPUJ) controls each control unit such as the keyboard/mouse control unit 11, disk control unit 14, display control unit 15, etc.
In addition to controlling the entire system, it also executes predetermined calculations, processing, etc.

The real memory 16 is comprised of a RAM, and stores therein an operating program for operating the system, a group of commands manually inputted from the keyboard 12 or the mouse 13, and a portion of a group of data as necessary.

The disk 17 also stores data that cannot be stored in the real memory 16, such as outline data and bit 1 map fonts (hereinafter referred to as
It's called a ``font.'' ) etc. are stored. The data stored on the disk 17 is read out from the disk 17 and stored in the real memory 16 under the control of the CPU I/O as necessary.

The display control unit 15 controls a display device 18 consisting of a bitmap display or the like, and displays the outline data of characters or figures as shown in FIG. 2 or the outline of a figure as shown in FIG. Displays a bitmap pattern as shown in the figure below, as well as windows corresponding to various functions.

In the font creation device having the above configuration, it is possible to modify and edit the outlines and bitmap patterns shown in FIGS. 2 and 3 displayed on the screen of the display device 18 using the mouse 13. That is, in the case of the outline shown in FIG. 2, the IQ R point 21 and the control point 2 provided at predetermined positions on the outline are moved by the cursor 20 that moves as the mouse 13 moves.
The CPUIO edits the outline again based on the designated modification position. Furthermore, in the case of the bitmap pattern shown in FIG.
Select the instruction, and then select the CPUI based on the specified correction position.
O is re-editing the bi-note map pattern.

Next, the operations for correcting and editing outline data and bitmap patterns will be explained based on the flowchart shown in FIG. In the figure, when a font correction/editing instruction is given by the user, the CPU 10 imports outline data corresponding to the instruction from the disk 17, stores it in a predetermined memory area of the real memory 16, and then controls the display control unit. 15 to draw strokes corresponding to the above outline data on the display device 18 to display an outline as shown in the embodiment of FIG. 2 (step 101). Then, when the control point 21 provided at a predetermined position on the outline and the correction position to which the control point 21 is to be moved are specified and selected by the cursor 20, the outline data in the real memory 16 is read in accordance with the above instruction. Correct/edit (step 102).

Next, the CPUIO develops a bitmap pattern in a predetermined memory area of the real memory 16 in accordance with the modified outline data, and generates bitmap patterns of characters and graphics as shown in the embodiment of FIG. A map font is created (step 103). The above bitmap font is created by converting all the dot information in the Out 1 line to "1", for example, and performing a filling operation to fill in the outline of a character or figure to generate a bitmap font.

Next, when a correction instruction is selected for a predetermined dot of the bitmap font using the cursor 20,
In response to the above instructions, the CPUI O modifies and edits the bitmap font in the real memory 16 to improve the quality of the font, and causes the display device 18 to display a bitmap pattern based on the bitmap font (
Step 1.04). Then, the user is asked whether the quality of the font is good (step 105).

Here, if there is an instruction from the user that the quality of the font is good, it is determined that the font is completed, the corrected/edited font is read from the real memory 16, and the font is stored in a predetermined memory on the disk 17. Store it in the area (
Step 106).

Furthermore, if the user indicates that the quality of the font is not good, the user is asked whether the amount of modification to the font is large or small (step 10).
7).

Here, if the user instructs that the amount of correction to the font is large, the process returns to step 102 and the outline data can be corrected/edited.
Repeat the above correction/editing operations. If there is an instruction from the user that the amount of correction to the font is small, the process returns to step 104 to enable the font to be corrected/edited, and the above correction/editing operation is repeated.

When the quality of the font becomes good and the modification/editing is completed, the completed font is stored in a predetermined memory area of the disk 17 (step 106), and the modification/editing operation is completed.

Therefore, in the present invention, when the amount of correction of the font specified by the user is large, the general correction is selected by correcting/editing the outline data, and when the amount of correction is small, the final correction is selected by correcting/editing the bitmap pattern. By selecting the final font corrections, you can easily create fonts with appropriate corrections, which improves the usability of the system. You can do L.

In addition, in the above embodiment, bitmap font correction/
Although the amount of correction is determined after editing, the present invention is not limited to this. For example, it is also possible to make the amount of correction be determined before modifying/editing the outline data. In this case, , an appropriate correction method can be selected from the initial correction/editing.

〔Effect of the invention〕

As explained above, in the present invention, it is possible to correct/edit outline data and bitmap patterns by appropriately selecting each correction method, so high-quality bitmap fonts can be created quickly and easily. be able to.
