TrueType is an outline font standard developed by Apple and Microsoft in the late 1980s as a competitor to Adobe's Type 1 fonts used in PostScript. It has become the most common format for fonts on the classic Mac OS, macOS, and Microsoft Windows operating systems.
The primary strength of TrueType was originally that it offered font developers a high degree of control over precisely how their fonts are displayed, right down to particular pixels, at various font sizes. With widely varying rendering technologies in use today, pixel-level control is no longer certain in a TrueType font.
TrueType was known during its development stage, first by the codename "Bass" and later on by the codename "Royal". The system was developed and eventually released as TrueType with the launch of Mac System 7 in May 1991. The initial TrueType outline fonts, four-weight families of Times Roman, Helvetica, Courier, and the Pi font replicated the original PostScript fonts of the Apple LaserWriter. Apple also replaced some of their bitmap fonts used by the graphical user-interface of previous Macintosh System versions (including Geneva, Monaco and New York) with scalable TrueType outline-fonts. For compatibility with older systems, Apple shipped these fonts, a TrueType Extension and a TrueType-aware version of Font/DA Mover for System Software 6. For compatibility with the Laserwriter II, Apple developed fonts like ITC Bookman and ITC Chancery in TrueType format.
