NAME

       Font::TTF::OldMort - Glyph Metamorphosis table in a font

DESCRIPTION

INSTANCE VARIABLES

       version
	   table version number (Fixed: currently 1.0)

       chains
	   list of metamorphosis chains, each of which has its own fields:

	   defaultFlags
	       chain's default subfeature flags (UInt32)

	   featureEntries
	       list of feature entries, each of which has fields:

	       type
	       setting
	       enable
	       disable
	   subtables
	       list of metamorphosis subtables, each of which has fields:

	       type
		   subtable type (0: rearrangement; 1: contextual substitution; 2: ligature; 4: non-contextual substitution; 5: insertion)

	       direction
		   processing direction ('LR' or 'RL')

	       orientation
		   applies to text in which orientation ('VH', 'V', or 'H')

	       subFeatureFlags
		   the subfeature flags controlling whether the table is used (UInt32)

	       Further fields depend on the type of subtable:

		   Rearrangement table:

		   classes
		       array of lists of glyphs

		   states
		       array of arrays of hashes{'nextState', 'flags'}

		   Contextual substitution table:

		   classes
		       array of lists of glyphs

		   states
		       array of array of hashes{'nextState', 'flags', 'actions'}, where "actions" is an array of two elements which are offsets to
		       be added to [marked, current] glyph to get index into "mappings" (or "undef" if no mapping to be applied)

		   mappings
		       list of glyph codes mapped to through the state table mappings

		   Ligature table:

		   Non-contextual substitution table:

		   Insertion table:

METHODS

   $t->read
       Reads the table into memory

   $t->out($fh)
       Writes the table to a file either from memory or by copying

   $t->print($fh)
       Prints a human-readable representation of the table

BUGS

       None known

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)
