Stroke foundation Chinese font small character quality display method and device

Abstract

The invention discloses a stroke foundation Chinese font small character quality display method and device. When Chinese font expressed in high resolution space is filled into lattice font image in low resolution, the problems that quality variation is produced and the image is unacceptable can not be avoided. The scheme provided by the invention is based on: Chinese font expressed by stroke foundation font data is adopted; the Chinese font is distributed on a lattice coordinate system; and the stroke shape of combined font is converted to generate new font; the new font is filled to generatea low resolution lattice font image with Chinese small character quality; wherein stroke shape converting on lattice space is judged according to sample of the stroke shape covered on a lattice pixeland covering value, the stroke shape converting includes that the sample information of the stroke covered on the lattice pixel is changed according to a key point for moving the stroke and width value for reducing the stroke, so as to avoid crowd between strokes and increase blank pixels between stokes, thus achieving the requirement of small character quality.

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 i...

Problems solved by technology

[0008] However, the problem with scalable fonts is that the quality of the fonts will deteriorate when displayed at low resolutions, because low-resolution fonts only allow a small number of pixels to form their image shapes. If the value is too large, graphics alienation will be caused by insufficient sampling, which will lead to deformation, especially when dealing with stroke-based Chinese fonts, because the strokes in the low-resolution space will stick together, causing the strokes to disappear and appear mottled image of black block

[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
