AppImage: Icon resolution

[rebio]

Short description The resolution of the AppImage icon varies.

Steps to reproduce Can not be reproduced within the program

Expected behavior Icon looks the same every time

Additional information AppImage used on KDE neon

The displayed resolution of the logo was way more pixelated in the past (like 8 x 8px). Then it got way better as it is shown for 3101. Now it get's worse.

I don't care much about the logo resolution. If you are not Captain Care'a'lot either feel free to close the report. I wanted to mention it as soon as I noticed it to avoid the unanswerable question which commit the change was caused by.

This could be because of the desktop environment. I downloaded the 3101 AppImage and the icon is 32x32, the same as the one you show for 3102.

I tested this on other DEs as well:

• ubuntu-22.04-desktop-amd64.iso (Ubuntu Gnome)
• neon-user-20220721-0952.iso (default KDE)
• elementaryos-6.1-stable.20211218-rc.iso (Pantheon)
• Fedora-Workstation-Live-x86_64-36-1.5.iso (default Gnome)
• manjaro-kde-21.3.5-220721-linux515.iso (KDE with manjaro branding)
• MX-21.1_KDE_x64.iso (MX KDE)

All tested DEs except one only showed a generic AppImage icon and not the RT icon. The one that did show the icon was KDE neon with default KDE (neon-user-20220721-0952.iso). So exactly what I use. Neither Gnome nor Pantheon displayed the icons. The strange thing: Other distros with KDE did not either.

I ran all systems from a live USB. I wouldn't expect that to be any different but I don't know for sure.

A bug report at the KDE bugtracker was closed as this problem is caused by the AppImage: https://bugs.kde.org/show_bug.cgi?id=456970

So they use the .DirIcon. The AppImage build process uses linuxdeploy to automatically generate that file. Unless there is an argument for using a specific resolution, I will leave it up to linuxdeploy to choose.

I don't know if anybody has changed the code for this, but 3151-ge5007c77 has a higher resoluted icon again

Thanks for the follow-up. So, the report is no longer valid?

[rebio]

Considering that the quality was changing in the past and switched through various resolutions I would wait until the next Automated build to really say more about this. If there was no change for a component regarding the building process or how the logo is handled I wouldn't expect that the random nature of this changed. Considering the pattern I observed, the chosen logo resolution seems to be somewhat random for each build. (3101 & 3151 = High resolution, 3102 = medium resolution, 3104 - 3140 = low resolution)

I noted it as soon as I observed it so it's easier to find the bug.

Looks like RawTherapee has been attacking the whiskey cabinet again.

Both 5.9 and dev AppImages appear fine now - closing as fixed.
