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.
