The reason G4 worked in the past was that it used tiff2pdf in the background. I switched to using PDF::API2 for the PDF engine in order to allow the use of the OCR layer behind the image.
Unfortunately, up to now, PDF::API2 has buggy G4 TIFF support, and so I disabled the G4 compression option in gscan2pdf. I have provided patches to the author of PDF::API2 to allow much better TIFF support, but these have not yet been accepted by the maintainer of PDF::API2. In the mean time, which later version of gscan2pdf still do not support G4, you would find lost of new features and bug fixes if you upgraded via the PPA. -- 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
