"""Regenerate Android launcher icons from piti-icon.png.
|
|
|
|
Usage: python3 tools/gen_launcher_icons.py
|
|
Requires: Pillow (pip install Pillow)
|
|
|
|
Produces, under app/src/main/res/:
|
|
- mipmap-<dpi>/ic_launcher.png legacy square (rounded), all densities
|
|
- mipmap-<dpi>/ic_launcher_round.png legacy round, all densities
|
|
- mipmap-<dpi>/ic_launcher_foreground.png adaptive-icon foreground (padded)
|
|
The adaptive XMLs (mipmap-anydpi-v26/) and the black background drawable are
|
|
checked in and don't need regenerating.
