# The AAT ‘cidg’ table has almost the same structure as ‘gidc’,
|
|||
|
|
# just mapping CIDs to GlyphIDs instead of the reverse direction.
|
|||
|
|
#
|
|||
|
|
# It is useful for fonts that may be used by a PDF renderer in lieu of
|
|||
|
|
# a font reference with a known glyph collection but no subsetted
|
|||
|
|
# glyphs. For instance, a PDF can say “please use a font conforming
|
|||
|
|
# to Adobe-Japan-1”; the ‘cidg’ mapping is necessary if the font is,
|
|||
|
|
# say, a TrueType font. ‘gidc’ is lossy for this purpose and is
|
|||
|
|
# obsoleted by ‘cidg’.
|
|||
|
|
#
|
|||
|
|
# For example, the first font in /System/Library/Fonts/PingFang.ttc
|
|||
|
|
# (which Apple ships pre-installed on MacOS 10.12.6) has a ‘cidg’ table.
