As I said, the file size depends heavily on the compression. You are using JPG compression, which is good for photo-type images, but not for scans of text.
The image is 8-bit, when 1-bit would have done. You say that you are using thresholding, but the log file doesn't show this. Try scanning with scan mode = lineart, and save the PDF with compression = auto. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/922162 Title: pdf output file is 6 times bigger than if created by simple-scan To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gscan2pdf/+bug/922162/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
