OKE_ST, STROKE_END, STROKE_
Weight indicates arrangement coordinates (start end and end coordinates) based on the end points of the core line of the stroke in the font design coordinate system (800 * 800 in this embodiment) and width information. By searching the stroke data from the stroke ID, the size D_STROKE of each stroke in the stroke design coordinate system, the weight information D_STROKE_Weight, and the control point data D_STROKE_POINT [] are read out.

FIG. 6 shows details of the character generation processing in step 2-2 of FIG. Step 6-1 is a process executed by the CPU 101 as a character expansion end determining means. CPU1
01 is the number of strokes and the STR
The number of strokes indicated by OKE_COUNT is compared, and if the development of all strokes is not completed, the process proceeds to step 6-2 to develop the remaining strokes, and if completed, the process proceeds to step 2-5 of FIG. Transition.

Step 6-2 is a process executed by the CPU 101 as the arrangement coordinate calculating means. Stroke arrangement coordinates (start and end coordinates) O_STROKE_ST and OSTROKE_EN in the character output coordinate system are calculated by the following equations.

[0040]

## EQU1 ## O STROKE ST = STROKE STx (OUT SIZE / 800) O STROKE EN = STROKE ENDx (OUT SIZE / 800) Step 6-3 is a process executed by the CPU 101 as a control point data scale conversion means.

[Equation 2] Scale = abs (O STROKE ST-O STROKE EN) / abs (D
STROKE ST-D STROKE EN)

[0042]

[Equation 3] Scale conversion of the stroke is performed by Scale x D STROKE POINT, and O_STR
Set to OK_POINT [].

Step 6-4 is a process in which the CPU 101 operates as stroke weight information adjusting means. If the weight in the character output coordinate system is O_Weight,

[0044]

[Equation 4] Weight Scale = O Weight / D STROKE A weight conversion scale is obtained from Weight, and stroke weight is adjusted to O_STROKE_POINT [].

Step 6-5 is a process executed by the CPU 101 as a stroke generating means and is related to the present invention. As described above, conventionally, when outputting a small size character, a thinning process has been performed to prevent the character from being crushed. However, in the stroke composite font method,
Since the thinning process is performed only for the intermediate control points of the basic character components because of the connection with the local contour, there is a problem that if the local contour does not exist, the tip of the stroke is not sharp and the length is degraded. there were. In the present embodiment, when there is no local contour on the stroke front side, the feature that is different from the conventional technique is that the stroke is sharpened by applying the thinning processing even to the tip of the basic character component.

FIG. 7 shows a stroke generation process for this purpose.

Step 7-1 is a process executed by the CPU 101 as a character size judging means. If the specified target font size is smaller than the specified font size,
The CPU 101 proceeds to step 7-2 to perform the stroke thinning processing. Otherwise, proceed to step 7-8.

Step 7-2 is a process in which the CPU 101 determines the vertical and horizontal strokes of all strokes from the stroke ID and skeleton data (stroke assembly information) as the determination means. If the stroke to be created is currently the stroke, step 7
-3, otherwise to step 7-4. Step 7-3 is a process in which the CPU 101 performs image correction of horizontal and vertical stroke thinning processing as thinning processing means.

As shown in FIG. 8, if the stroke to be created is a horizontal stroke, the control points A and B on the bottom side are moved upward by one dot, and if the stroke is a vertical stroke, the control point C on the right side of the stroke. , D to the left by one dot.

Step 7-4 is also a process executed by the CPU 101 as stroke thinning processing means. As shown in FIG. 9, thinning processing is performed on the middle point of the stroke control points. Step 7-5 is a process executed by the CPU 101 as a determining means for determining whether or not a local contour exists on the stroke tail side. If the stroke assembly information includes information about the local contour, the local contour is included in the generated stroke. Is determined to exist, the process proceeds to step 7-7. If there is no local contour, the process proceeds to step 7-6. Step 7-6 is a stroke tail side thinning processing executed by the CPU 101 as tail side thinning processing means.
As shown in 0, the image correction of the thinning process is performed on the stroke tail portion.

Step 7-7 is a process in which the CPU 101 performs local contour joining on the stroke tail portion as a local contour joining means. As shown in FIG. 11, assuming that the weight data of the stroke connecting portion is A and the weight data of the connecting portion of the local contour is B, the CPU 101 causes the tangent vectors AA and B.
A transformation matrix is calculated with the inner product of B being θ, and this scaling matrix is applied to the control points of the local contour.

Steps 7-8 are processes executed by the CPU 101 as a judgment means for judging whether or not the local contour of the stroke head portion exists. If a local contour exists, the process proceeds to step 7-9, and if not, step 6-
Move to 6.

Step 7-10 is C as a judgment means for judging whether or not the local contour of the stroke tail portion exists.
This is the process executed by the PU 101. If the local contour exists, the processing procedure shifts to Step 7-11, and if it does not exist, shifts to Step 7-8. By determining the presence or absence of the above-described local contour (data), it is possible to perform the image correction of the thinning processing on the character pattern having no local contour in the tail portion of the stroke and sharpen the shape of the tip of the stroke.

When the above stroke generation processing is completed, the procedure moves to step 6-6 in FIG.

In step 6-6, the CPU 101 sets the generated (created) stroke (image form) in the output buffer. Of course, after all strokes have been developed and created, the created result may be set as character data in the output buffer.

The created result, that is, the character pattern (bitmap data) is displayed on the CRT 106 or P in accordance with the external instruction.
It is transferred to the RT 110 and is visually output.

As described above, according to this embodiment,
When outputting a small size character in the stroke composite font method, the thinning process for the body part of the stroke can be executed or not executed according to the form of the character. More specifically, when the local contour of the tail portion does not exist in a part of the character, the tail portion can be thinned to correct the shape of the stroke tip and significantly improve the character quality.

(Other Embodiment 2) Next, a second embodiment of the present invention will be described.

What is handled here is a relative stroke thickening process in the stroke generation process of the first embodiment. The local contour size of local contours such as splashes and scales, which tend to be reduced by a smaller character size, is retained, and the character quality can be greatly improved. Hereinafter, the stroke generation processing, which is a difference from the first embodiment, will be described.

FIG. 12 shows the details of the stroke generation processing. In step 12-1, the CPU 101 proceeds to step 12-2 for performing stroke thinning processing when the generation target character size is smaller than the prescribed character size, and otherwise proceeds to step 12-11.

Step 12-2 is a process in which the CPU 101 functions as a judgment means for judging vertical and horizontal strokes from the stroke ID and skeleton data. If the stroke to be generated is the corresponding stroke,
Move to step 12-10, otherwise step 1
Move to 2-3.

Step 12-10 is a thinning process of horizontal and vertical strokes. As shown in FIG. 8, if the stroke to be generated is a horizontal stroke, the control points A and B on the bottom side are moved to the upper part of one dot. If the stroke to be generated is a vertical stroke, the thinning processing is realized by moving the control points C and D on the right side of the stroke to the left by one dot.

Step 12-3 is also stroke thinning processing, and as shown in FIG. 9, thinning processing is performed at the middle point of the stroke control points. Step 12-4 is a process of determining whether or not a local contour exists on the stroke tail side,
If the local contour exists, the process proceeds to step 12-5, and if it does not exist, the process proceeds to step 12-8. Step 12-
Reference numeral 5 is a process for determining whether or not to perform a thickening process on the stroke tail portion based on the stroke ID. That is,

[0064]

[Outside 1]

A stroke having the shape of a splash or scale is judged, and if the stroke to be generated is the corresponding stroke, the process proceeds to step 12-6, and if it is any other stroke, the step 12-7 is performed. Transition.

In step 12-6, the stroke tail portion is thickened. More specifically, the thickening process is performed as shown in FIG. Since the size of the local contour is proportional to the weight of the stroke tail portion, this processing makes it possible to hold the local contour size of a splash, a scale or the like that tends to be reduced. Step 12-7 is a process of performing local contour joining on the stroke tail portion.

Step 12-8 is a process for judging whether or not the local contour of the stroke head portion exists. If the local contour exists, the process proceeds to step 12-9, and if it does not exist, step 6-6 in FIG. Return to. Step 12-1
1 is a process for determining whether or not there is a local contour of the stroke tail portion, and if there is a local contour, step 1
2-12, and if there is not, it moves to step 12-8. By the above processing, the character quality is greatly improved by maintaining the size of the local contour portion such as a splash or scale which tends to be reduced by a small character.

The strokes of the character pattern subjected to the above-described image processing are set in the output buffer as in the first embodiment. Of course, all strokes may be expanded into an image and then set as character data in the output buffer.

The set character pattern is output to the CRT 106 or PRT 110 according to a display or print instruction.

As described above, according to the present embodiment,
In the stroke composite font method, when outputting a small size character, the body part of the stroke is thinned. At this time, for a stroke having a local contour such as a tooth scale, the tail portion is thickened. As a result, it is possible to maintain the local contour size of the splashes, scales, etc., which tends to be reduced, and to greatly improve the character quality.

In addition to this embodiment, the following example can be carried out.

1) The line width of the strokes that form a character differs depending on the typeface. Therefore, the character size to be subjected to the thinning processing can be changed according to the typeface. In this case, the correspondence table of the fonts and the character sizes to be thinned is stored in the ROM 102.
The CPU 101 may refer to this correspondence table when a character is generated and determine whether or not to perform the thinning process.

2) In the present embodiment, the thinning processing or the thickening processing is realized by moving the coordinate points of the character, but by deleting the dots on the outer periphery of the character image after occurrence,
The line width can be thickened by supplementing the line width and increasing the number of dots adjacent to the outer circumference.

3) Various methods are conceivable as a method of determining whether or not there is a local contour based on the stroke combination information. The first is a method of selectively using the meaning of the stroke ID for a stroke having a local contour and a stroke having no local contour. The second is a method of determining that there is no local contour when the number of coordinates of the local contour is 0. Also, regarding the stroke tail portion and the head portion, the CPU 101 can determine the type by fixing the storage location of the coordinate point data or adding the identification information.

4) In the present embodiment, the thickening processing of the local contour is performed so as to match the line segment of the connection portion of the character basic element which has been thickened. However, depending on the special character, the thickening processing may be performed only on the local contour portion. May be done.

[0076]

As described above, according to the present invention,
A character line segment having no local contour such as splashes and scales of a character has a sharp tip, and the character has high quality.

Further, according to the present invention, small size characters have high quality.

Further, in the present invention, the processing time is prevented from being lengthened by not processing the vertical and horizontal strokes.

The character generating device of the present invention can be applied to a printing device.

The character generator of the present invention can be applied to a display device.

Further, according to the present invention, the advantage of the stroke synthesizing font method is utilized, and the information for generating the character pattern is changed, so that the correction process becomes simpler than the image correction of the dot image.

Further, according to the present invention, even when a character pattern smaller than a predetermined size is generated, the character splashes,
Since the character portion of the local contour such as the scale portion is locally thickened, the character is not lost as in the conventional case, and the character has high quality.
