imagetopaa

Open-source CLI that converts PNG/TGA images to Bohemia Interactive .paa textures (DXT1/DXT5) for Arma 3 mods.

Alternative to the proprietary ImageToPAA.exe from Arma 3 Tools.
Supports soft alpha, mipmaps, and atomic writes.

Usage after install:
imagetopaa input.png output.paa
imagetopaa icon.png icon.paa --format dxt5
imagetopaa solid.png solid.paa --format auto --force
