OSError: cannot write mode RGBA as JPEG #44
Description
Hello,
Thanks for this tool, I'm trying to process diff on a PDF of 250 pages plus and getting this error. It works with 'png' format but it barely readable and images reader hangs because the file is too large...
Calling
% pdf-diff -f jpeg v1.pdf v2.pdf > diff.jpeg
I Get:
Traceback (most recent call last):
File "/usr/local/lib/python3.8/site-packages/PIL/JpegImagePlugin.py", line 614, in _save
rawmode = RAWMODE[im.mode]
KeyError: 'RGBA'
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "/usr/local/bin/pdf-diff", line 8, in <module>
sys.exit(main())
File "/usr/local/lib/python3.8/site-packages/pdf_diff/command_line.py", line 499, in main

OSError: cannot write mode RGBA as JPEG
I'm on macOS Catalina.
Thanks for your help :)
