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 preceded 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 preceded 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

       •   No support for format 2 tables (MBCS)
