Font::TTF::OldCmap - Character map table
This module is deprecated
Looks after the character map. The primary structure used for handling a cmap
is the the Font::TTF::Segarr manpage 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 the Font::TTF::Segarr manpage can work quite happily without it).
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 the Font::TTF::Segarr manpage which contains the content of the particular
subtable.
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.
Given a Unicode value in the MS table (Platform 3, Encoding 1) locates that
table and looks up the appropriate glyph number from it.
Finds the Microsoft Unicode table and sets the mstable instance variable
to it if found. Returns the table it finds.
Writes out a cmap table to a filehandle. If it has not been read, then
just copies from input file to output
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.

No support for format 2 tables (MBCS)
