Python imaging alternatives

Question

I have python code that needs to do just a couple simple things to photographs: crop, resize, and overlay a watermark. I\'ve used PIL, and the resample/resize results are TERRIB

Answer 1

Last time I compared, this downscaler's output is almost identical to that of GIMP's "cubic" option:

 import Image

 def stretch(im, size, filter=Image.NEAREST):
     im.load()
     im = im._new(im.im.stretch(size, filter))
     return im

IIRC, the differences are visually indistinguishable -- some pixel values +/-1 due to rounding, and they tend to be round the edges. It's not slow either.
