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 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->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

BUGS

       o   No support for type 4 tables

NAME

       Font::TTF::Loca - the Locations table, which is intimately tied to the glyf table

DESCRIPTION

       The location table holds the directory of locations of each glyph within the glyf table. Due to this relationship and the unimportance of
       the actual locations when it comes to holding glyphs in memory, reading the location table results in the creation of glyph objects for
       each glyph and stores them here.  So if you are looking for glyphs, don't look in the "glyf" table, look here instead.

       Things get complicated if you try to change the glyph list within the one table.  The recommendation is to create another clean location
       object to replace this table in the font, ensuring that the old table is read first and to transfer or copy glyphs across from the read
       table to the new table.

INSTANCE VARIABLES

       The instance variables do not start with a space

       glyphs
	   An array of glyph objects for each glyph.

       glyphtype
	   A string containing the class name to create for each new glyph. If empty, defaults to Font::TTF::Glyph.

METHODS

   $t->new
       Creates a new location table making sure it has a glyphs array

   $t->read
       Reads the location table creating glyph objects (Font::TTF::Glyph) for each glyph allowing their later reading.

   $t->out($fh)
       Writes the location table out to $fh. Notice that not having read the location table implies that the glyf table has not been read either,
       so the numbers in the location table are still valid. Let's hope that "maxp/numGlyphs" and "head/indexToLocFmt" haven't changed otherwise
       we are in big trouble.

       The function uses the OUTLOC location in the glyph calculated when the glyf table was attempted to be output.

   $t->out_xml($context, $depth)
       No need to output a loca table, this is dynamically generated

   $t->glyphs_do(&func)
       Calls func for each glyph in this location table in numerical order:

	   &func($glyph, $glyph_num)

BUGS

       None known
