The problem seems to be with the embedded alpha channel in the TIF. It is always using the alpha when you try to do anything with the file. Is there an easy way to avoid this? In my case, I need the full image without the alpha.
Currently, if you open the TIF and display it, it will only show you the image thru the alpha.
