[Linux] AppImage Icon doesn't get set with programs like AppImageLauncher

[dginovker]

When using AppImageLauncher, the AppImage Icon doesn't get set when you "Run and Integrate" the .AppImage into your system.

Error log:

./RuneLite.AppImage 
WARNING: No icons found at "usr/share/icons"
WARNING: Using .DirIcon as default app icon
ERROR: Unable to load image.
ERROR: No icon was generated for: /home/dr_bracket/Applications/RuneLite_a89cceadeb287b5371332a93cb025628.AppImage
WARNING: Unable to resize the application icon into a 128x128 image: "Unable to load image.". It will be written unchanged.
WARNING: Unable to resize the application icon into a 256x256 image: "Unable to load image.". It will be written unchanged.

Then the installation looks like this:

Instead of this:

I'm not entirely sure why, during my debugging of build-linux.sh, the .DirIcon in the warning shows up in the native-linux folder as it should.

Only tested on Arch Linux - Will test on KUbuntu shortly.

On KUbuntu I get effectively the same warning, but no error:

** (process:4784): WARNING **: 17:13:57.693: No icons found in AppDir/usr/share/icons. Using .DirIcon as fallback

It'd be great if the .DirIcon worked 🤔

Judging by https://docs.appimage.org/reference/appdir.html, I think you would just have to copy an icon into the appdir right around here: https://github.com/runelite/launcher/blob/master/build-linux.sh#L62 ?

Unless I'm doing the copying wrong, I can't seem to get it to work. That said, someone smarter should probably look at it rather than trusting me 😄

I think it's
cp ../../appimage/RuneLite.png .DirIcon

[dginovker]

The .DirIcon has always been there, it's just not getting read for some reason. Maybe it's a bug in AppImageLauncher? (Although it's been this way for as long as I can remember)

are you sure? I don't think so

Could probably just symlink it to runelite.png actually.

I think this might be a bug in AppImageLauncher. libappimage tries to detect .DirIcon as png (or an svg, alternatively) but fails. None of the pngs I tried worked, but an svg did. What also worked was putting a copy of the icon in usr/share/icons; files in there just get copied to ~/.local/icons from what I can tell.
