Method for displaying the quality of small characters in stroke-based Chinese fonts

Abstract

The invention discloses a method for displaying the quality of stroke-based Chinese characters in small characters. Filling Chinese glyphs expressed in high-resolution space into low-resolution dot-matrix font images will inevitably lead to unacceptable problems of poor quality. The solution provided by the present invention is based on: using stroke-based fonts The Chinese glyphs represented by the data; arranging the Chinese glyphs on the dot matrix coordinate system; converting the strokes of the combined glyphs to generate new glyphs; and filling the new glyphs to generate low-resolution dot matrix font images with the quality of small Chinese characters; among them, in The transformation of the stroke shape in the dot matrix space is based on the samples and coverage values ​​of the strokes covered on the dot matrix pixels. The transformation of the stroke shape is to change the sample information of the strokes covered on the dot matrix pixels by moving the key points of the strokes and reducing the width value of the strokes. , to avoid strokes crowding each other and increase the blank pixels between strokes to meet the quality requirements of small characters.

Description

technical field [0001] The present invention relates to the technology of generating low-resolution small-character quality display based on outline font data, especially a method and device for generating low-resolution Chinese character small-character quality display based on stroke basic font data. Background technique [0002] Generally, the technology that is widely used in the generation and display of Chinese fonts in computers belongs to the generation method of stroke-based fonts. This technology has also been disclosed in Chinese patent case number ZL99100827.8, the generation of stroke-based font data Contains two processes. The first process is to define a basic stroke set. Each basic stroke is to describe the generation of strokes belonging to the same stroke category by formulating some parameters. The second process is to use the fully defined basic strokes Set to combine Chinese characters, so as to generate the data of each stroke parameter value combined ...

Problems solved by technology

[0009] The phenomenon of low-resolution Chinese quality degradation can be more clearly understood in the following disclosure, that is, the direct projection of stroke glyphs described in high-resolution space The technical problem of displaying in a low-resolution space is that the graphics quality of the original description cannot be completely maintained, especially when projected to a relatively low resolution, it is unacceptable
