摘要： A method for compressing font instruction data. The method includes analyzing a set of pixel-per-em values and fractional pixel shifts contained in font instruction for each glyph in a font data set to construct a database of values. The pixel-per-em values and fractional pixel shifts are converted into operational codes and argument values and these values are compressed into a compressed data stream including a series of multiple-bit words representing font instruction specifications for each glyph in the font data. In addition, fixed environmental variable values are set for each glyph based on the font instruction data. When a glyph is to be rendered using the compressed font instruction, the compressed instruction is decompressed and only relevant multiple-bit word or words corresponding to font instruction specifications for the respective glyph are executed, but not any of the 16-bit words corresponding to font instruction for the fixed environmental values.

摘要： A computer system for rendering text is provided. A keyboard is used to enter characters into the computer system. A character code corresponding to each entered character is generated. A particular font is chosen from a font table stored in memory. The font table contains a number of different fonts, with each font having a number of glyph indexes corresponding to a number of different glyphs. A character can have a plurality of different glyph indexes for a particular font. A processor maps the character code to a glyph index according to the selected font and later processes the glyph index. The glyph corresponding to the processed glyph index is then displayed.

摘要： Data tables that are required for the proper processing of font glyphs are automatically synthesized if they do not form part of an original font definition. The synthesized tables are stored in an annex file that is associated with the font, rather than being incorporated into the font definition. As a result, the integrity of the original font data is maintained, and does not adversely affect font protection systems that are based upon font data.
