You may see a good performance boost by using interpolation='nearest'. Also, with your clip changes and with Eric's changes is it still painfully slow for you -- how much have these changes helped? Of time time spent in make image, how much is _image.fromarray, ScalarMappable.to_rgba and _image.resize? ------------------------------------------------------------------------- Take Surveys.
