"""Android launcher icons from an app's icon.svg.
|
|
|
|
python3 tools/app_icons/android_mipmaps.py apps/translator
|
|
|
|
Renders <app>/resources/icon.svg to 1024 px with macOS QuickLook, cuts it to
|
|
its rounded square (radius 224/1024, the corners QuickLook paints white) and
|
|
writes <app>/resources/icon_1024.png plus resources/android/res/mipmap-*/ic_launcher.png,
|
|
which `cargo makepad android` picks up. Authoring only; nothing at build time
|
|
runs it. Needs Pillow.
