[Bug 23963] New: Visible reduction in image quality
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23963 Bug ID: 23963 Summary: Visible reduction in image quality Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: major Priority: P5 - low Component: Tools Assignee: koha-bugs@lists.koha-community.org Reporter: martin.renvoize@ptfs-europe.com QA Contact: testopia@bugs.koha-community.org CC: bibliwho@gmail.com, jonathan.druart@bugs.koha-community.org, katrin.fischer@bsz-bw.de, magnus@libriotech.no, mtj@kohaaloha.com, testopia@bugs.koha-community.org, wizzyrea@gmail.com Depends on: 21987, 22988 +++ This bug was initially created as a clone of Bug #22988 +++ RM NOTE: This bug is a placeholder to note that we are reverting bug 21987 whilst we work on the main issue for a longer term resolution to bug 22988 in that bug. I have a library that is noticing a visible reduction in image and thumbnail quality after upgrading from 18.11.03 to 18.11.05. This could be a regression from bug 21987. They have a lot of scanned black and white covers. The largest text in the thumbnails used to be readable, but after the upgrade, it is not. Their scanning process has not changed, so the original image that they upload should be of the same quality as before. Old, good image: http://bibliotek.dis-danmark.dk:8080/cgi-bin/koha/catalogue/image.pl?imagenu... http://bibliotek.dis-danmark.dk:8080/cgi-bin/koha/catalogue/image.pl?imagenumber=4332&thumbnail=1 New, not so good, image: http://bibliotek.dis-danmark.dk:8080/cgi-bin/koha/catalogue/image.pl?imagenu... http://bibliotek.dis-danmark.dk:8080/cgi-bin/koha/catalogue/image.pl?imagenumber=4463&thumbnail=1 Did we reduce the quality a bit too much?

Martin and Fridolin, I've recently been contacted by a Koha site on 19.05.06 reporting they're still having issues with images. I have 3 images but could only attached 1. This Koha site reports:
The top example is from before the upgrade. - clear and crisp The bottom 2 are from after the upgrade - blurred
Images that come in automatically from online are clean/clear, but many of the images I add myself. There was no change in the quality of the images, but it changed with the upgrade.
Thanks! Curious as to what is happening with this...
It has been reverted as it caused regressions, see bug 22988. -- You are receiving this mail because: You are watching all bug changes.
