-=head1 NAME
-
-Font::TTF::Post - Holds the Postscript names for each glyph
-
-=head1 DESCRIPTION
-
-Holds the postscript names for glyphs. Note that they are not held as an
-array, but as indexes into two lists. The first list is the standard Postscript
-name list defined by the TrueType standard. The second comes from the font
-directly.
-
-Looking up a glyph from a Postscript name or a name from a glyph number is
-achieved through methods rather than variable lookup.
-
-This class handles PostScript table types of 1, 2, 2.5 & 3, but not version 4.
-Support for version 2.5 is as per Apple spec rather than MS.
-
-The way to look up Postscript names or glyphs is:
-
- $pname = $f->{'post'}{'VAL'}[$gnum];
- $gnum = $f->{'post'}{'STRINGS'}{$pname};
-
-=head1 INSTANCE VARIABLES
-
-Due to different systems having different limitations, there are various class
-variables available to control what post table types can be written.
-
-=over 4
-
-=item $Font::TTF::Post::no25
-
-If set tells Font::TTF::Post::out to use table type 2 instead of 2.5 in case apps
-can't handle version 2.5.
-
-=item VAL
-
-Contains an array indexed by glyph number of Postscript names. This is used when
-writing out a font.
-
-=item STRINGS
-
-An associative array of Postscript names mapping to the highest glyph with that
-name. These may not be in sync with VAL.
-
-=back
-
-In addition there are the standard introductory variables defined in the
-standard:
-
- FormatType
- italicAngle
- underlinePosition
- underlineThickness
- isFixedPitch
- minMemType42
- maxMemType42
- minMemType1
- maxMemType1
