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 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};

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
           cannot 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->read
       Reads the Postscript table into memory from disk

   $t->out($fh)
       Writes out a new Postscript name table from memory or copies from disk

   $t->XML_element($context, $depth, $key, $val)
       Outputs the names as one block of XML

   $t->minsize()
       Returns the minimum size this table can be. If it is smaller than this, then the table
       must be bad and should be deleted or whatever.

BUGS

       •   No support for type 4 tables
