[Bug 1016824] Re: Ubuntu wallpapers are low quality (low resolution, JPEG artefacts, noise)
Hello Daniel; thank you for the comment. While the point about dithering may be valid different issue though; one of style/technical choices; rather than of JPEG compression. Would you be able to file it as a new, separate issue, if you'd still like to follow it up? ** Changed in: ayatana-design Status: New = Fix Released ** Changed in: ubuntu-branding Status: New = Fix Released ** Changed in: ubuntu-wallpapers (Ubuntu) Status: Confirmed = Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016824 Title: Ubuntu wallpapers are low quality (low resolution, JPEG artefacts, noise) To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/1016824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Marking as Fixed, as the core issue of size restrictions leading to high-compression is hopefully resolved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016824 Title: Ubuntu wallpapers are low quality (low resolution, JPEG artefacts, noise) To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/1016824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Technically my comment in the description about increasing image smoothness to eliminate noise is not resolved at all. But yeah, I'm not going to bother fighting to keep this bug open right now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016824 Title: Ubuntu wallpapers are low quality (low resolution, JPEG artefacts, noise) To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/1016824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Update: In bug 1081702, design has mentioned that they intentionally dither the default Ubuntu wallpaper image so that it looks OK on 6-bit LCDs (18-bit colour). I find this disappointing because it reduces the image quality (dithering = grainy) for everyone who has a 24-bit display. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016824 Title: Ubuntu wallpapers are low quality (low resolution, JPEG artefacts, noise) To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/1016824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Because we no longer have CD space limitations, the new wallpaper is 2560x1600 and compressed using a lossless format, so hopefully this fixes two of the issues mentioned here ;-) See bug #1081702 for further discussion. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016824 Title: Ubuntu wallpapers are low quality (low resolution, JPEG artefacts, noise) To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/1016824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Still seeing this in the latest quantal wallpaper. The default purple wallpaper is grainy and looks low quality. The others in quantal are better than precise though. ** Description changed: Ubuntu wallpapers are low quality. They often are low resolution, have JPEG artefacts and/or visible noise. This degrades the quality feel of the desktop itself. The low resolution is self explanatory. Many people use a monitor resolution that is 1920 pixels wide. This should be easy to support as even the lowest quality digital camera is higher resolution than that. By comparison, gnome-backgrounds uses mostly 2560x1600 or 1920x1200. Often JPEG artefacts are visible in areas of very slight gradation. Though in precise I think there is a bigger problem with noise. Neither of these should be visible on the desktop. Please increase the JPEG encoding quality, and the image smoothness before that. Compare ubuntu-wallpapers with those from gnome-backgrounds. Though gnome-backgrounds are not great quality either, they are far better prepared than ubuntu-wallpapers. - - I repeat: This degrades the quality feel of the desktop. ** Also affects: ubuntu-wallpapers Importance: Undecided Status: New ** Also affects: ayatana-design 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/1016824 Title: Ubuntu wallpapers are low quality (low resolution, JPEG artefacts, noise) To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/1016824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
