[Image-SIG] Does PIL not handle TIFFs created on Mac OS X?

[Tom Bridgman]

Hi,

My installation reads this file under OS X, but I have a slight patch
which I describe in my post last week for handling TIFFs with
Extrasamples=1.

Perhaps you need to update SAVE_INFO as well.

I'm not sure if this is the RIGHT way to do it, but it seems to read the
file okay.

Was this generated by RenderMan?
