Definition: TrueType

A scalable font technology that renders fonts for both the printer and the screen. Originally developed by Apple as a competitor to PostScript, the technology was licensed by Microsoft for Windows. Included with the operating system starting with Mac OS 7 in 1991 and Windows 3.1 in 1992, TrueType fonts have been widely used in all successive versions.

The Font Contains the Rules
Unlike PostScript and other font technologies, in which the rendering algorithms are maintained in the rasterizing engine, each TrueType font contains its own algorithms for converting the outline into bitmaps. The lower-level language embedded within the TrueType font allows unlimited flexibility in the design. See TTF file, OpenType and TrueImage.
