NAME¶
Font::TTF::GrFeat - Graphite Font Features
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.
