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

   $t->print($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.
