font::ttf::post(3)
NAME
Font::TTF::Post - Holds the Postscript names for each
glyph
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 vari
able 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};
INSTANCE VARIABLES
Due to different systems having different limitations,
there are various class variables available to control
what post table types can be written.
- $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. - VAL Contains an array indexed by glyph number of
- Postscript names. This is used when writing out a
font. - STRINGS
- An associative array of Postscript names mapping to
the highest glyph with that name. These may not be in
sync with VAL. - In addition there are the standard introductory variables
defined in the standard:
FormatType
italicAngle
underlinePosition
underlineThickness
isFixedPitch
minMemType42
maxMemType42
minMemType1
maxMemType1
METHODS

$t->out($fh)
