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

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.
