  • Publication number: 20130155098
    Abstract: A computing device-implemented method includes analyzing a set of executable instructions that define an outline of a font glyph for assigning points of the outline into two or more groups. The method also includes manipulating the points assigned to the two or more groups for adjusting the displayed appearance of the font glyph.

  • Patent number: 8044961
    Abstract: 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.

  • Patent number: 7719537
    Abstract: 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.

  • Patent number: 7379075
    Abstract: Colors are specified within the individual glyphs of a font by means of an indirect approach which employs multiple tables. The data values for individual pixels of a glyph identify entries in an index table, which pertains to a subset of all available colors. The entries in the index table map to a complete set of colors that are specified in a color table. As a result of this structure, the amount of data that is required to specify the individual pixels of a glyph can be minimized to the number of bits required to distinguish the colors within that glyph. The specification of all available colors within a single table permits that table to be shared among various resources, including bitmap fonts and outline fonts.

  • Patent number: 5416898
    Abstract: 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.
