Abstract
A font compression method and apparatus operates by: compressing different components of a font file with separate compressors having varying compression schemes to produce a plurality of intermediate compressed data sets; separating compressed glyph table components of the font file into different ones of the intermediate compressed data sets; and further compressing the intermediate compressed data sets to produce corresponding compressed output data sets. A corresponding decompression method and apparatus is used to decompress fonts which have been compressed using the above method.
