I ported the amazing and simple to use libGDX texture packer to Allegro:

Allegro-Texture-Packer on GitHub

All documentation is in the link above. Now you can easily pack your images to improve drawing efficiency. Enjoy

That's really neat. Here's some docs on it for those curious what it does:

Every one should be aware of this. You seem to have designed it well, too. Thank you for sharing.

Thanks for your kind words! The texture packer API allows you to drop it in and replace your existing bitmap drawing calls with barely any changes.

Really great! This feature of LibGDX has always been awesome, but I have always preferred Allegro. Thank you!
