Abstract
A method of creating font format data from source font data includes analyzing the source font data to obtain glyph data for a plurality of glyphs, dissecting the glyph data, extracting midline data from the dissected glyph data, classifying the midline data as unique element data and common element data, associating unique element data and common element data to each glyph of the plurality of glyphs.
Claims10
A method for rendering text from stored font data, comprising:
- receiving at a rendering engine a request to render a glyph;
- in response to the request, the rendering engine accessing a font data structure stored in a computer readable medium, the font data structure including common element data and unique element data for a plurality of glyphs;
- the rendering engine constructing a glyph skeleton using the common element data and unique element data;
- and
- the rendering engine rendering the glyph for display using the glyph skeleton.

A mobile communication device, comprising:
- a computer readable medium;
- a font data structure stored in the computer readable medium, the font data structure including common element data and unique element data for a plurality of glyphs;
- an application program configured to request glyphs for display on the mobile communication device;
- and
- a rendering engine configured to:
- receive a request from the application program to render a glyph;
- in response to the request, access the font data structure to identify common element data and unique element data for the glyph;
- construct a glyph skeleton using the identified comment element data and unique element data;
- and
- render the glyph for display using the glyph skeleton.
