Abstract
The present invention is aimed at three specific data areas of font compression, each of whose size has become significant as other data areas have been compressed. The three data areas include model factoring, character level feature measurement (local dimensions) factoring, and typeface level feature measurement (global dimensions) factoring. In general, the invention in each area is an apparatus and method used in font compression to reduce redundant information, thereby allowing a reduction in data format (e.g., words to bytes and bytes to bits) resulting in an overall reduction in storage area for a given font collection.
