TrueType is a scalable font technology designed by Apple Computer, and now used by both Apple and Microsoft in their operating systems. TrueType fonts offer the highest possible quality on computer screens and printers, and include a range of features which make them easy to use.
A TrueType font file contains data, in table format, that comprises an outline font. Rasterizers use combinations of data from the tables contained in the font to render the glyph outlines.
