The code responsible for encoding pdf is available here: https://gitlab.gnome.org/GNOME/simple-scan/-/blob/master/src/book.vala#L348
It is comparing jpeg with zlib: https://gitlab.gnome.org/GNOME/simple-scan/-/blob/master/src/book.vala#L479 How would you like to change it? What do you think about setting quality to maximum, force zlib compression? ** Changed in: simple-scan (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to simple-scan in Ubuntu. https://bugs.launchpad.net/bugs/1886279 Title: simple-scan pdf compression Status in simple-scan package in Ubuntu: Incomplete Bug description: Hello, PDF compression cannot appropriately be configured. Having taken a look at the latest source code of simple-scan: 1) simple-scan compresses each image in ZLIB or JPEG depending on the compressed size (it keeps the ZLIB version if it is smaller than the JPEG) 2) the "quality" setting only applies to JPEG With this in mind, I think it is impossible to use simple-scan to create a PDF full of lossless ZLIB images for archiving documents where we want to keep quality at the expense of the size.
