That looks like the effect one gets when the pixel depth is wrong, or the target word width gets miscalculated etc. Try checking the various width & height values that get calculated, the bits per pixel, stuff like that. Remember also that we have to mangle pixels being read from outside files because our pixel value 0 is transparent and not black!
