Public bug reported:
I am using scribus 1.4.6+dfsg-4build1 on Ubuntu 17.10 (artful). Create a
new Scribus document and just insert one JPG compressed picture
(Sleeping_hedgehog.jpg in my example). Then export this document as PDF.
Use following settings in Image Compression Method:
Compression Method: Automatic
Compression Quality: Maximum
Unticked Maximum Image Resolution
The resulting PDF is multiple times bigger than the original JPG
picture:
$ du -sh *
23M Example_automatic_high.pdf
23M Example_automatic_maximum.pdf
23M Example_automatic_medium.pdf
2,9M Example_jpeg_maximum.pdf
23M Example_lossless_maximum.pdf
12K Example.sla
2,2M Sleeping hedgehog.jpg
I expected that the resulting PDF just embeds the JPG picture without
modifying it, but this is not the case. I don't see a way to let Scribus
embed all JPG/PNG images unmodified in the PDF.
