What does the original look like? You need to test step by step to see at what point it goes wrong. You're scaling by 20 (which is a massive amount); what happens when scaling by 1? And anti-alias is turned off? (Which might let you see by how many pixels each successive line is out and could give a clue.) It does seem as though something is going amiss with recognising the image dimensions, or you've inadvertently applied a 'shear' or 'slant' transformation. (Maybe you can apply a reverse transform to fix it!) -- Bartc
