Description

Control method and control system for font strokes, computer equipment and computer readable storage medium
Technical Field
The invention relates to the technical field of character and graphic processing, in particular to a control method of font strokes, a control system of font strokes, computer equipment and a computer readable storage medium.
Background
The word stock is an indispensable part in modern operating systems, and assists various devices in displaying fonts and the like. And a set of word stock needs to go through a complicated flow before being put into use, except that a font designer designs a word draft and accurately draws each font at the earlier stage, a tool is also needed to further process and check the word stock, so that the word stock can be well displayed in the system. The process of further processing the font library includes adding some instructions to the font, such as controlling the thickness of the horizontal and vertical strokes to be consistent, adjusting the rendering effect under each font size, adjusting the font strokes under each font size to achieve a better display effect, and the like.
The control of the consistency of the thickness of the horizontal strokes and the vertical strokes means that certain rules are added to the horizontal strokes and the vertical strokes to control the consistency of the width of the strokes so that the strokes can display correct effects in the system. Since the rule is mainly used for controlling the consistency of the thickness and the width of the stroke, the rule is in a form of a pair, and relates to line segments on two sides of the stroke, and each side at least comprises one line segment. The method for adding rules to horizontal and vertical strokes is mainly used for some competitive word stocks, such as blackbodies, songhs and the like, which are common, for example, the radical of ' grass ' + ', as shown in fig. 1, the upper and lower horizontal line segments in the circle 1 and the upper and lower four horizontal line segments in the circle 2 should belong to a group of rules, that is, the upper horizontal line segments in the two circles are both the upper sides of the rules, and the lower horizontal line segments are both the lower sides of the rules, so that the heights of the upper or lower horizontal line segments in the two circles can be synchronously controlled, and the strokes are uniform in thickness. However, if the strokes in the two circles do not belong to a group of controls (i.e., the upper and lower horizontal line segments in circle 1 form a group of rules, and the upper and lower horizontal line segments in circle 2 form a group of rules), the situation that the widths of the strokes of the upper (or lower) horizontal strokes in circle 1 and circle 2 are inconsistent in some display environments may occur, thereby affecting the display effect. And the character quantity of a set of Chinese character library is the least simple character library, and more than 6000 Chinese characters exist, so that for the problems, manual adjustment consumes time and labor, and tools are required for processing, adjusting and judging.
The effect of the existing common tool on most of font plus horizontal and vertical stroke rules is good, but some problems still exist, such as rule plus bold or rule plus not, and the like, so that the stroke width is not easy to control, wherein the rule plus not plus condition is mainly adopted, if the rule plus not plus condition is adopted, the display effect of a word stock in a system is poor, meanwhile, the time cost of manual verification is increased, and the working efficiency is reduced.

(2) if j is equal to i +1, if j is equal to N, the operation goes to (6), otherwise, the operation goes to (3);
(3)Riand RjIf the distance between the two points is smaller than the stroke width minimum value, returning to the step (2), if the distance between the two points is larger than the stroke width maximum value, switching to the step (6), and otherwise, switching to the step (4);

the deleting unit is specifically configured to delete the any pair of horizontal ruled lines or the any pair of vertical ruled lines if the determination result is negative.
8. The system for controlling glyph strokes of claim 7, wherein the first judging unit further comprises:
the second judgment subunit is used for judging whether the same line segment simultaneously exists in the N pairs of deleted horizontal ruled lines or deleted vertical ruled lines;
the deleting unit is specifically further configured to delete N-1 pairs of the deleted horizontal ruled lines or the deleted vertical ruled lines if the determination result is yes;
wherein N is an integer greater than 1.
9. The system for controlling glyph strokes of claim 6, wherein the obtaining unit specifically comprises:
the first obtaining subunit is used for obtaining the font outline according to the font loop of the font;
and the second acquisition subunit is used for determining the inner contour and the outer contour according to the inner and outer directions of the font contour.
10. The system for controlling glyph strokes of claim 6, wherein the dividing unit further comprises:
and the sequencing unit is used for sequencing the horizontal contour line segments of all the components in sequence from top to bottom and sequencing the vertical contour line segments of all the components in sequence from left to right.
11. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the steps of the method of controlling glyph strokes according to anyone of the claims 1 to 5 when executing the computer program.
12. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of a method of controlling glyph strokes according to anyone of the claims 1 to 5.
