Abstract
A method for automatically converting an outline font character into a glyph-based font character using a set of predefined basic glyphs stored in a glyph database is provided. Each basic glyph is predefined as a program for rendering the basic glyph for output. Additionally, each basic glyph is associated with a glyph signature consisting of feature points, and script sentences that obtain key points and width values based on the feature points. According to the automatic font conversion method, first, an outline font character to be redefined is captured. Then, one glyph is selected from the captured character. Thereafter, feature points are identified along the outline of the selected glyph and stored in a glyph signature. Next, the glyph database is searched and a basic glyph that topographically matches the selected glyph is retrieved. Next, the script sentences associated with the retrieved basic glyph are used together with the identified feature points of the selected glyph to obtain key points and width values for the selected glyph. Thereafter, the selected glyph with its key points and width values is stored as a program for rendering the selected glyph for output. At th…
