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

POD ERRORS

       Hey! The above document had some coding errors, which are explained below:

       Around line 11:
	   '=item' outside of any '=over'

       Around line 114:
	   You forgot a '=back' before '=head1'

NAME

       Font::TTF::OldCmap - Character map table

       This module is deprecated

DESCRIPTION

       Looks after the character map. The primary structure used for handling a cmap is the Font::TTF::Segarr which handles the segmented arrays
       of format 4 tables, and in a simpler form for format 0 tables.

       Due to the complexity of working with segmented arrays, most of the handling of such arrays is via methods rather than via instance
       variables.

       One important feature of a format 4 table is that it always contains a segment with a final address of 0xFFFF. If you are creating a table
       from scratch this is important (although Font::TTF::Segarr can work quite happily without it).

INSTANCE VARIABLES

       The instance variables listed here are not preceeded by a space due to their emulating structural information in the font.

       Num Number of subtables in this table

       Tables
	   An array of subtables ([0..Num-1])

       Each subtables also has its own instance variables which are, again, not preceeded by a space.

       Platform
	   The platform number for this subtable

       Encoding
	   The encoding number for this subtable

       Format
	   Gives the stored format of this subtable

       Ver Gives the version (or language) information for this subtable

       val This points to a Font::TTF::Segarr which contains the content of the particular subtable.

METHODS

   $t->read
       Reads the cmap into memory. Format 4 subtables read the whole subtable and fill in the segmented array accordingly.

       Format 2 subtables are not read at all.

   $t->ms_lookup($uni)
       Given a Unicode value in the MS table (Platform 3, Encoding 1) locates that table and looks up the appropriate glyph number from it.

   $t->find_ms
       Finds the Microsoft Unicode table and sets the "mstable" instance variable to it if found. Returns the table it finds.

   $t->out($fh)
       Writes out a cmap table to a filehandle. If it has not been read, then just copies from input file to output

   @map = $t->reverse([$num])
       Returns a reverse map of the table of given number or the Microsoft cmap. I.e. given a glyph gives the Unicode value for it.

BUGS

       o   No support for format 2 tables (MBCS)
