Abstract
An image font file is created containing compressed bitmap representations of the characters of one or more fonts utilized for a given text. These compressed bitmap representations are derived as character image templates corresponding with a font of an enlarged size. Upon being conveyed to client software, the individual characters of the image font file are accessed, and while remaining in a compressed format are selectively shifted in accordance with typesetting specification error values, then scaled and filtered to produce a display character in anti-aliased, sub-pixel position format.
