CID-keyed fonts
CID-keyed fonts represent the basic underlying technology used for building today’s (and
tomorrow’s) PostScript CJKV fonts. CID stands for Character ID, and it is a character
and glyph access type for PostScript. Technically speaking, a CID-keyed font is a Type 0
(composite) font with FMapType 9. A CID-keyed font can also be CIDFontType 0, 1, or
2, depending on the type of character descriptions that are included. CIDFontType 0 is by
far the most common CID-keyed font.
ere are two components that constitute a valid a CID-keyed font: a CIDFont resource
that contains the glyph descriptions (outlines), along with other data necessary to prop-
erly render them, such as hinting information; and one or more Character Map (CMap)
resources that are used to establish character-code to CID mappings. e CIDs are ulti-
mately used to index into the CIDFont resource for retrieving glyph descriptions.
A valid CID-keyed font instance consists of a CIDFont plus CMap concatenated using
one or two hyphens.
