Abstract

PURPOSE:To deform characters only by calculating such process as character modification and rotation based on a calculation formula and to attain also character enlargement, character reduction, the deformation of a mirror body, etc., by transforming bit map information into coordinate arrangement data. CONSTITUTION:The system is constituted of a character pattern generating device 2 and a controller 1 which controls the device. The controller 1 is provided with a full-dot character generating device control part 1,1 which controls a full-dot character generating device and a deformed character generating mechanism 1,2. Then, by transforming the character bit map information of the character pattern generating device 2 into the coordinate arrangement and performing an adding/subtraction operation with respect to the transformed coordinate arrangement, characters are rotated, modified, displayed on a CRT screen, and printed on a printer. Thus, such deformed character generation as the character rotation and the character modification can be performed only by transforming the coordinate arrangement data.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a modified character generation method for character patterns.

[Conventional technology]

In the conventional (conventional) character rotation/character modification method, the bitmap information of the character pattern was directly rotated/decorated to process the bitmap.

[Problem to be solved by the invention]

For example, in the conventional character rotation method described above, each rotation type (90 degrees, is o 1m, 270 degrees) is used.
Each bitmap is processed according to the data, and those rotated by 90 degrees and those rotated by 270 degrees are processed separately. Also, rotation, enlargement, reduction, mirroring, and modification processing are performed separately. Each requires dedicated processing and was divided into phases.

[Means to solve the problem]

The modified character generation method of the present invention includes a character pattern generation device and a controller that controls the device. The controller controls a full-dot character generator control section and a modified character generation mechanism that control the full-dot character generator.

[Effect]

The modified character generation method of the present invention converts the character bitmap information of the character pattern generator into a coordinate array and performs addition/subtraction operations on the transformed coordinate array. It is displayed on the CR'V screen and printed on the printer.

[Example 51 Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram 71777 which does not show an example of this method.

The modified character generation system of this embodiment is comprised of a full dot character generator control section 1.1, a deformed character generator side 12, and a full dot character generator 2.

Figures 1 and 2 show the main routine of the character generator control unit 1 shown in Figure 1 and the operational flow 11 of the modified character generator 11. The main routine of the full-dot character generator program ``1'' is activated and 17 is activated from the application program.

When a request for a modified character is received from an application program, the bitmap information of the corresponding character is extracted from the No. 1'n routine of the character generator control unit shown in Fig. 2. Then, in judgment 1, if there is a modification request in the requested character, P> If there is a request, the process branches to the modified character generation routine 'i tel(a >).

In the modified character generation routine shown in FIG. 3(a), in process 3, the hit map information of the modified fine character pattern is ordered in the X direction and the Y direction as shown in FIG. [￥1(, J Shizu-sama (, lX, Y)
Convert to coordinate array. In judgment 2, it is determined whether there is a modification request, and if there is, the process branches to the modification processing routine of 1st 1 +-71 (b).

In this modification processing routine, i! It is determined by Jl cut 4 whether there is a request for a bold character included in the modification, for example, and if there is a request, the process branches to process 7, a routine for calculating the uppercase character coordinate array 31.

In the coordinate array calculation routine for bold characters in process 7, (7) the data is converted into coordinate array data using the calculation formula shown in the figure, and the coordinate array data is added.

In judgment 5, it is determined whether there is a rotation request, and if there is, the process branches to the rotation processing routine shown in FIG. 3(e).

In this rotation processing routine, it is determined whether the example slag has been rotated by 90 degrees based on judgments 1. If there is, process 8. :/)90
Branches to the degree coordinate array calculation routine.

In the 90 degree coordinate array calculation routine of process 8, the coordinate array data is converted using the calculation formula shown in FIG.

The result is as shown in Figure 8.

In the form entry 6, the result of the coordinate array f-ta shown in FIG. 8 is converted into a re-display map, and the conversion result is returned to the requesting application program. The flow is almost the same as 180/270 degree rotation and 0 degree rotation.

FIG. 9 shows each dot I-image of the character pattern after inverse conversion.

〔Effect of the invention〕

As explained above, the present invention converts -degree and bitma/tsubu information into coordinate array data, so that processes such as character modification and rotation can be transformed simply by calculating based on calculation formulas. For transformations such as enlargement, reduction, and mirror objects, just by changing the calculation formula, the appearance becomes "l'tihi" and has the effect of sharing the program logic with the Q1 finger.
