Public bug reported: A while ago, I reported a regression because G4 compression did not work any more in recent versions of ubuntu: https://bugs.launchpad.net/ubuntu/+source/gscan2pdf/+bug/482673 .
My bug report led to the disablement of G4 compression. This somehow restores user satisfaction, but if I remember right, G4 compression had much better results in Black/white (2 colors) color mode than all the other compression algorithms. I also think that the bug not originates in gscan2pdf itself but either in a library which is used by gscan2pdf or in wrong usage of the interface of such a library. Now that G4 compression worked perfectly fine in earlier versions of ubuntu and gscan2pdf, my question would be if G4 compression could please be enabled again. It might even happen that just by reverting the older patch (for 482673) already does the trick in case the library has been fixed in the meantime (which is many years in that case). Currently, I'm using ubuntu 16.04 and gscan2pdf 1.3.9, but I'm planning to upgrade to ubuntu 18.04 soon. ** Affects: gscan2pdf (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784120 Title: Reenable G4 compression in gscan2pdf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gscan2pdf/+bug/1784120/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
