JP2 failed to put in PDF correctly when handling color images #8980

When I use Pillow to resave your image as a PDF, here is the resulting file that I get - sam.pdf When I view the PDF, I don't see a problem. The image that you provided is in RGBA mode. This makes me think this is a recurrence of #8074, where Pillow was creating a well-formed PDF, but there is a bug in the viewer that prevents it from displaying it correctly. What program are you using to view the PDF? What version of that software are you using? If you view your PDF in a browser, does it display correctly? If you are looking for a workaround, I expect converting the image to RGB will work. from PIL import Image
l = [Image.open(f"Barcarolle-000{p}.jp2") for p in range(1, 7)]
l[0].convert("RGB").save("sam.pdf", "PDF") |

Okay, I checked the program, and it is indeed envice (packaged in Pop!OS, GNOME 42.9). And it is totally fine in browser, yes. The workaround is also working. Thanks you for solving this! |
What did you do?
Changing colour JP2 images from Library of Congress to PDF format.
What did you expect to happen?
Simply format change and should expect a properly showed colour pdf.
What actually happened?
Decoding faulted and resulted in overlaying pdf.
What are your OS, Python and Pillow versions?
The original image:
Barcarolle-0001.zip
The result file cannot be uploaded as GitHub does not allow me uploading that large of a file.
Here is a screenshot:
Notice that this only affects colour images. Grayscale and B/W works out just fine without any distortions.
