Addons
The community of Allegro users have contributed several library extensions to handle things like scrolling tile maps and import and export of various file formats (e.g. PNG, GIF, JPEG images, MPEG video, Ogg, MP3, IT, S3M, XM music, TTF fonts, and more). There are also bindings for several programming languages available, such as Python, Perl, Scheme, C#, D and others.
Allegro 4.x and below can be used in conjunction with OpenGL by using the library AllegroGL which extends Allegro's functionality into OpenGL and therefore the hardware. Allegro 5 natively supports OpenGL.
