Icon generator for Android and iOS made with Lazarus FPC and BGRABitmap
https://github.com/lainz/lainzicongenerator/releasesDrop an image into the window, select an output folder, and you have all icon resolutions created.
I will upload Linux and macOS builds soon. Done.
This generates all the icons / splash screen / loading screen used by a multi device application made with Delphi, but it can be easily tweaked to generate any icon resolution.
Lazarus can target Android as well, so I think it can be usefull here too.
