package Font::TTF::Post;

=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
cannot 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
