Treating method and its use for dynamic Chinese character word library containing writing time sequence information

Abstract

The present invention provides processing approach of dynamic Chinese character font library containing write order information. The processing approach includes processing static Chinese character image to extract the strokes and extract the contour and skeleton of each stroke in the write order; tracing the time sequence information of stroke skeleton and time sequence information of the stroke contour in preset policy; and performing sectional curve fitting and time sequence information fitting to convert the input static Chinese character information into dynamic Chinese character data. The present invention may be applied for dynamic display of Chinese characters in various styles and simulating dynamic Chinese character writing process. The present invention has also static zooming and dynamic restoring function of Chinese characters, and is suitable for various fields where dynamic Chinese character display is needed.

Description

technical field [0001] The invention relates to computer image data processing and Chinese character information processing technology, in particular to a design and data processing method of a curved dynamic Chinese character library. Background technique [0002] With the development of computer glyph description technology, the Chinese character font library technology has evolved through the stages of bitmap bitmap and vector font library, and has now developed to the stage of curve outline font library. Vector fonts in PostScript format and various curved outline fonts represented by TTF (True Type Font) and OTF (Open Type Font) formats overcome the shortcomings of the original bitmap fonts in terms of fixed font size and large data storage capacity , making full use of curve (Bessel function or B-spline function) simulation technology for contour simulation, which solves the problem of font smooth scaling and greatly reduces storage space. With the maturity of font te...

Problems solved by technology

[0003] Whether it is the traditional vector font or the currently popular TTF, OTF, PS fonts, they all have a common disadvantage, that is, their application is limited to static display, these fonts do not store the stroke order information of Chinese characters, and most of the fonts only contain outlines Data, although a small number of databases are composed of strokes-parts-Chinese characters in a hierarchical combination method, there is still no information about stroke order and Chinese writing, so dynamic display cannot be performed

The current rapidly developing fields of computer-aided Chinese teaching, multimedia font animation design, etc. not only have requirements for the effect of static display, but also have special requirements for the dynamic display of Chinese character writing. The current static curve outline font library cannot meet this aspect. Require

The current dynamic Chinese character fonts are basically processed by third-party tools (such as PhotoShop, Flash), the storage capacity is huge, the production process is complicated, and the fonts are incomplete, inflexible, and inconvenient to promote; although these fonts are partially solved It overcomes the defect that traditional static fonts do not contain stroke order information, and can realize the time sequence display of Chinese characters, but the playback effect of these fonts is uneven, and the form is relatively simple. In terms of data storage structure, it is mostly in the form of bitmap, which cannot be realized. Changes such as font scaling and rotation are not in line with the current curve outline font technology
