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.AUTHOR
