PSD incorrectly loaded

[gverm]

What did you do?

I opened the TIFF in Pillow and converted it to JPG.

What did you expect to happen?

The JPG image to look the same as the original TIFF.

What actually happened?

The converted JPG looks malformed and has messed up colors.

What are your OS, Python and Pillow versions?

• OS: Linux
• Python: 3.10.5
• Pillow: 9.1.1 (also tested -git)

>>> img = Image.open("3662b8bd397337482862ab1a06bf3366-OA_535_161_17_F_TE.tif")
>>> out_img = img.convert("RGB")
>>> out_img.save("converted.jpg", quality=95)

original image (beware, 274MB)
converted image

Is it okay to report this here or should I report this to the appropriate library (libtiff, jpeg-turbo, ?)

Here is the right place to report it - taking a look, your file is actually not a TIFF, but a Photoshop file. The fact that we're not loading it correctly has nothing to do with those other libraries.

@radarhere My bad, I should have checked the mimetype...

I've concluded that your PSD file has an alpha channel, and that Pillow isn't correctly handling RGBA PSD files.

I've created PR #6481 to resolve this.
