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)
