Font::TTF::GrFeat - Graphite Font Features
DESCRIPTION INSTANCE VARIABLES
version
features
An array of hashes of the following form
feature feature id number
name name index in name table
exclusive
exclusive flag
default the default setting number
settings
hash of setting number against name string index
METHODS
$t->read
Reads the features from the TTF file into memory
$t->out($fh)
Writes the features to a TTF file
$t->print($fh)
Prints a human-readable representation of the table
$t->tag_to_num ($feat_str)
Convert an alphanumeric feature id tag (string) to a number (32-bit). Tags are normally 4 chars. Graphite ignores space padding if it is
present, so we do the same here.
$t->num_to_tag ($feat_num)
Convert a feature id number (32-bit) back to a tag (string). Trailing space or null padding is removed. Feature id numbers that do not
represent alphanumeric tags are returned unchanged.
BUGS
The version 1 Feat table ends with a feature (id 1) named NoName with zero settings but with an offset to the last entry in the setting
array. This last setting has id 0 and an invalid name id. This last feature is changed to have one setting.

Font::TTF::OldCmap(3) User Contributed Perl Documentation Font::TTF::OldCmap(3)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)
