BTW, are you sure you want un-premultiplied images? pre-multiplied images are often handy.

I think it's semantically supposed to always return pre-multiplied alpha images.
Okay, so maybe a conditional define or read option is due?
Definitely, NOT a conditional define. Some way of specifying whether pre-multiplied images should be returned would be nice although I don't know offhand how you would do this without breaking ABI compatibility. You probably shouldn't expect to see it in libtiff unless you're willing to contribute suitable patches. :)
