Abstract

PURPOSE:To display characters at high speed and to load character data without needing a special mechanism by holding the form of a graphic character as a program to function as one part of a graphic drawing means. CONSTITUTION:When a letter A is registered by form data consisting of six points (x1, y1)-(x6, y6) by a character data registering means 1, a character data accumulating means 2 generates character form data 23 and a character code table 22 and accumulates them in a character data accumulating medium 5. Next, a character development processing program 6 generated by a character development program generating means 3 is translated into an object format by a compiler 4. When a graphic is drawn, an application program 8 gives a character code to a graphic drawing means 9. The graphic drawing means 9 calls a character string displaying means 10. The character string displaying means 10 calls a character development processing program 7 and displays the character form data as segments on a graphic display device 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a graphic character registration and display method for registering the shape of one graphic character and displaying the graphic character in graphic processing by a computer.

[Conventional technology]

In conventional graphic processing systems, the shape data of one graphic character was held as a character font file, or the font data was loaded into a special memory area using a special mechanism before graphic drawing.

[Problem to be solved by the invention]

In the above-described method of holding character shape data in the character font file, it is necessary to input the file when drawing nine-figure characters, which may deteriorate performance. Also 2
The method of loading character font data into a special memory area prior to graphic drawing required a special mechanism, including the operating system.

[Failure to solve the problem]

The graphic character registration and display method according to the present invention is as follows.

A character data registration means for generating shape data of a graphic character and a character code corresponding to the character, and a character data storage means for storing the generated character data.

A character expansion processing program generation means for generating a character expansion processing program that generates character shape data from a two-character code based on the accumulated character data.

The apparatus further includes character string display means for displaying characters corresponding to character codes instructed by the application program on the graphic display device by using the character expansion program when drawing graphics.

〔Example〕 Next, two aspects of the present invention will be explained with reference to the drawings.

FIGS. 1 and 2 are block diagrams showing the configuration of an embodiment of the present invention.

Figure 1 shows the configuration of the stage of registering 2-character data and generating a 9-character expansion processing program.Character data registration means 1 creates and registers 1-character data, and character data storage medium 5 stores 2-character data. A character expansion processing program generating means 3 generates a character expansion processing program in a source program format by referring to the character data in the one character data storage means 2 and the two character data storage medium 5 stored in the It consists of a computer program 4 to be translated and a character expansion processing program 7 in an object program format obtained thereby.

FIG. 2 shows an application program 8 that instructs the drawing of two figures,
Character string display means 1o and character string display means 10, which are called when graphics drawing means 9 performs drawing processing upon receiving instructions from application program 8, display characters, inquire about the shape of characters. It consists of a character expansion processing program 7 and a graphic display device 11 that ultimately displays characters.

FIG. 3 is a logical explanatory diagram of a pig generated in the process of this embodiment. Figure 3(a) shows character data registration means 1.
This is an example of registering the English letter A in Figure 3(b).
shows the logical format of the character data generated by the character data storage means 2, and FIG. 3(c) is an example of the calling format of the character expansion processing program generated by the character expansion processing zologram generation means 3. be.

In FIG.
When registering (xlyl) to (as shown in Figure 3(a))
X6. If it is decided to register the shape data consisting of 6 points of y6), the 2-character data storage means 2.

As shown in FIG. 3(b), a character code table 23 is generated, which is composed of a pair of character shape data 23 consisting of the coordinates of line segments constituting nine characters, a two-character code, and a pointer to the corresponding character shape data. death.

It is stored in the character data storage medium 5.

Next, the character expansion processing program generating means 3 refers to the stored character data and generates a character expansion processing program 6 in the form of a source program. The generated character expansion processing program has one subroutine at tS shown in FIG. 3(c) and has two arguments.

The first argument C0DE is the character code given when calling this subroutine, and the second argument STR is the return value of this subroutine, which contains the character shape data corresponding to the character code given in the first argument C0DE. return.

In the example in Figure 3, if the first argument C0DE is given the alphabetic letter A, the second argument STR is (xl y yl) ~
Six points (x6 y y6) are returned.

The generated character expansion processing program 6 in the source program format is translated into an object format by the controller 4.

When drawing a figure in FIG. 2, the application program 8 gives a nine-character code to the two-figure drawing means 9 when instructing it to draw a figure character. When the graphic drawing means 9 is instructed to draw two graphic characters, it calls the nine character string display means 10. The character string display means 10 calls the character expansion processing program 7 by giving the character code given from the application program 8 as an argument.

Character shape data corresponding to the given character code is obtained and the data is sent to the graphic display device 11 as a group of line segments. Due to the breakage, graphic characters are displayed on the two-graphic display device 11.

〔Effect of the invention〕

As explained above, the present invention is capable of registering the shapes of arbitrary graphic characters and retains the shapes of nine graphic characters as a program that functions as a part of graphic drawing means.
There is no need for film input/output, and characters can be displayed at high speed.

It does not require any special mechanism for loading character data, and has the advantage of being easily implemented.
