>From https://bugs.scribus.net/view.php?id=10505:
"A(nother) user recently noted on irc that progressive mode JPEG induced huge PDFs, when not-progressive type just did fine PDFs (i'm not sure but i seem to remember that this user said it was a new behaviour)." This is exactly my problem. When I convert the picture and remove the progressive mode, the resulting PDF is small. ** Bug watch added: Scribus Mantis Bug Tracker #10505 https://bugs.scribus.net/view.php?id=10505 ** Also affects: scribus via https://bugs.scribus.net/view.php?id=10505 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to scribus in Ubuntu. Matching subscriptions: scribus https://bugs.launchpad.net/bugs/1748634 Title: Automatic image compression produces huge PDF files (corverts JPG to bitmap) Status in Scribus: Unknown Status in scribus package in Ubuntu: New Bug description: 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.
