DESCRIPTIONEach device table corresponds to a set of deltas for a particular point over a range of ppem values.
- The first ppem value in the range
- The last ppem value in the range
- This is an array of deltas corresponding to each ppem in the range between first and last inclusive.
- This is the fmt used (log2 of number bits per value) when the device table was read. It is recalculated on output.
newCreates a new device table
readReads a device table from the given IO object at the current location
out($fh, $style)Outputs a device table to the given IO object at the current location, or just returns the data to be output if $style != 0
$d->signature()Returns a content based identifying string for this delta for compression purposes
$d->out_xml($context)Outputs a delta in XML
