Note Submitter: ceo at l-i-e dot com ---- Unlike, say, imagecolorallocate, this function would seem to be using 1/0 for success/failure (respectively) as a return value. Or, at least, 1 for success anyway... I didn't work real hard at coming up with a way to make it fail to be sure it's 0 on failure...
