[Image-SIG] RGBA support in TIFF imgaes...

[Kevin Cazabon]

I'm just wondering if there's any reason that RGBA images aren't properly supported
in the TIFF reader... I realize that the documentation doesn't mention RGBA for TIFF,
however the images do load without error (they load as RGBX), but the alpha channel
is messed up.

I'm using RGBA images for combining images with masks, by doing:

background.paste(im, (0,0), im)

(where im is an RGBA file)

It works fine for PNG and TGA files, but not TIFF.

Is it supposed to work, or is there something that needs to be changed in the TIFF
plugin?

Thanks,
Kevin Cazabon.
