Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] Such as figure 1 Shown, the concrete steps of method of the present invention are as follows:

[0027] Step 1, establish the mapping relationship between the two glyphs.

[0028] The connected area of ​​the glyph is the component, which divides the components of the glyph, and calculates the matching degree of each component between the two glyphs according to the characteristics of the center, area, and spatial position of each component. The pair of components with the highest matching degree has a mapping relationship.

[0029] Step 2: Carry out maximum convex subdivision for each part.

[0030] Each part of the glyph is subdivided based on the Delaunay triangulation method, and the triangulation results are merged so that each polygon after the subdivision of the parts reaches the maximum subdivision.

[0031] Step 3, establishing a convex polygon mapping rela...

Abstract

The invention discloses a font synthetic method based on an improved expansion algorithm. The method comprises the following steps that: firstly, independently carrying out convex decomposition on each component of two fonts, establishing a mapping relationship among the components, and establishing a convex polygon mapping relationship in the corresponding component; then, utilizing a matching edge characteristic to carry out expansion on the convex polygon with the mapping relationship and process an expansion result; and finally, carrying out curve fitting on the expansion result to realize the synthesis of Chinese character fonts. The method disclosed by the invention has the advantages of good font synthesis effect, high synthesis quality and the like.

Description

technical field [0001] The invention relates to the field of text and graphics processing, in particular to a font synthesis method with an improved expansion algorithm. Background technique [0002] Glyph synthesis is a kind of graphics deformation technology, which belongs to a new branch in the field of graphics processing. For graphics, it can generate new glyphs through existing glyphs, which is an important research topic. Glyph synthesis refers to generating a series of intermediate glyphs based on two existing glyphs through a certain algorithm, so as to achieve a smooth transition between the two glyphs. Most of the existing font synthesis methods are based on glyph images, that is, font synthesis is performed on the basis of images. However, the graphics-based font synthesis methods mostly deal with glyphs with the same topological structure. [0003] The prior art discloses a variety of glyph synthesis methods, and the processing objects are mostly glyphs with ...
