Set the output compression for colour to JPEG

Posterize some of the colour / grayscale images

Generate the output.

This posterized images fail to save. No error shown.

The console show the following:
JPEGSetupEncode: PhotometricInterpretation 3 not allowed for JPEG.

Expected

  • show an error in case of failure: there is still a slight hint that it failed as the ? in the thumbnail is here.
  • automatically fallback to lzw for for this PhotometricInterpretation
