NAME
       PDF::API3::Compat::API2::Basic::TTF::Cmap - Character map table

DESCRIPTION
       Looks after the character map. For ease of use, the actual cmap is held
       in a hash against codepoint. Thus for a given table:

	   $gid	= $font->{'cmap'}{'Tables'}[0]{'val'}{$code};

       Note that $code should be a true	value (0x1234) rather than a string
       representation.

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 A hash keyed	by the codepoint value (not a string) storing the
	   glyph id

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)
       Finds a Unicode table, giving preference	to the MS one, and looks up
       the given Unicode codepoint in it to find the glyph id.

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

   $t->ms_enc
       Returns the encoding of the microsoft table (0 => symbol, etc.).
       Returns undef if	there is no Microsoft cmap.

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

   $t->XML_element($context, $depth, $name, $val)
       Outputs the elements of the cmap	in XML.	We only	need to	process	val
       here

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

   is_unicode($index)
       Returns whether the table of a given index is known to be a unicode
       table (as specified in the specifications)

BUGS
       o   No support for format 2 tables (MBCS)
