Definitions for "Scalable Font"
(see outline font)
A font that lets a user vary character point size (pitch). The characters are composed of mathematically defined "designs" that can be enlarged or reduced to produce a desired pitch. Outline fonts are also called scalable fonts.
Any font that is defined by mathematical routines that can reproduce the outlines of each character at any size. Macintosh System 7, vector, PostScript, and TrueType fonts are all scalable; raster (bitmap) fonts are not.
