NAME
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->minsize()
Returns the minimum size this table can be. If it is smaller than this,
then the table must be bad and should be deleted or whatever.
$t->print($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.
