At the same time, the data of the shaded character pattern edited from the above data is temporarily stored.

The character pattern memory 16 stores, for example, as shown in FIG. 3A, the data content of each character pattern of the font structure, the display bit map of each character pattern, and the like. The shadow pattern memory 17 stores data contents of a shadow pattern in which black and white data are arranged according to a predetermined rule, a shadow pattern display bitmap, and the like, as shown in FIG. 3B, for example. ing.

The video RAM 18 is stored under the control of the CPU 10 and is stored in the main memory 15, for example, as shown in FIG.
Under the control of the control unit 14, the stored data of the shaded character pattern is read.

In the above-mentioned character / graphic editing device, when editing a shaded character, display the property of each editable font composition name on the screen of CRT19 based on the font composition editing program of the shadow character pattern, The desired font configuration name is selected and displayed with the mouse 13 to edit the shaded characters. Hereinafter, FIGS. 2 and 3
The editing operation of the shaded character will be described in detail with reference to the drawings.

FIG. 2 is a flow chart showing the editing operation of the shaded characters, and FIG. 3 is a diagram showing each pattern in the process of the editing operation. In FIG. 2, first, it is judged whether there is an instruction to edit a shaded character (step 10
1) When the user gives the editing instruction, the CPU 10 reads a desired character pattern (see FIG. 3 (a)) corresponding to the instruction from the character pattern memory 16 and stores it in the main memory 15 (step 102). . Next, the CPU 10 reads an arbitrary shadow pattern (see FIG. 3B) of the same size as the character pattern from the shadow pattern memory 17 and stores it in the main memory 15 in the same manner.

Next, the CPU 10 performs a logical operation on the character pattern and the shadow pattern on the main memory 15 (step 103). If the output level of the black data of the character pattern and shadow pattern data is set to the low level and the output level of the white data is set to the high level, the logical operation (hereinafter referred to as “OR”) is performed. If the output level of the black data is set to the high level and the output level of the white data is set to the low level, the logical product (hereinafter referred to as “AND”) operation is performed. A pattern as shown in FIG. 3 (c) is obtained.

If the above pattern yields a predetermined pattern, then
The CPU 10 multiple-writes the obtained predetermined pattern several times (four times in the embodiment) while diagonally shifting it by one dot (step 104). The overwriting is performed by AND condition when the output level of black data of the data of the predetermined pattern is set to the low level and the output level of the white data is set to the high level. Is set to the high level and the output level of the white data is set to the low level, the OR condition is used. And
When the overwriting pattern as shown in FIG. 3 (d) is obtained by the overwriting of the predetermined pattern, the CPU 10 adds the original shown in FIG. 3 (a) to the above-mentioned overwriting pattern obtained by the overwriting. Overlay the character pattern of (step 10
Five). The overwriting is performed by AND condition when the output level of the black data of the character pattern and the data of the overwriting pattern is set to the low level and the output of the white data is set to the high level. If the data output level is set to the high level and the white data output level is set to the low level, the OR condition is used.
Therefore, a shaded character pattern as shown in FIG. 3E is generated on the main memory 15, and the shaded character pattern is stored in the video RAM 18 under the control of the CPU 10.

When the shaded character pattern is stored in the video RAM 18, the CRT control unit 14 controls the CRT 19 to read the data of the shaded character pattern of the font configuration stored in the video RAM 18, and to the shaded character pattern. The corresponding bitmap can be displayed on the screen of the CRT 19 (step 106).

In addition, in the present invention, the data of the character pattern and the data of the shadow pattern are stored in the memory in the system, but it is also possible to store the data in an external storage device such as a disk to perform the editing operation of the shaded characters. Is.

As described above, in order to generate a shadow character pattern from a normal character font pattern such as Mincho or Gothic font and a shadow pattern in response to a user's request for editing a shadow character, the shadow character pattern is generated. It is possible to eliminate the need to store it in a memory or the like in advance.

〔The invention's effect〕

As described above, in the present invention, a desired character font pattern and a shadow pattern are logically operated to create a font pattern having the outline of this character font pattern and a shadow pattern. A double writing pattern is created by performing a logical operation between the created font pattern and a shift pattern in which the coordinate position of the font pattern is shifted by a predetermined amount, and the character font pattern is superimposed on the created double writing pattern to create a shaded character pattern. Since it is configured to create the above, it is not necessary to store the shaded character pattern in the memory in advance, the memory capacity required for storing the font can be reduced, and the production cost can be reduced.

Further, in the present invention, a desired character font pattern is die-cut from a shadow pattern, a font pattern having the outline of the font pattern and having a shadow pattern design is created, and then this font pattern is appropriately shifted. However, since the logical operation is performed, it is possible to diversify the shadow portion of the shaded character pattern.
