If you skip both libtiff makes assumption that you have a strip for every component. I don't know why libtiff operates in such way, probably there was some reasoning in the first place. So just set the ImageHeight and problem should go away. Best regards, Andrey -- Andrey V. Kiselev Home phone: +7 812 5970603 ICQ# 26871517
