allegro_qoi/sample.c

// This program simply loads a QOI file into Allegro
// as a texture and then dumps the texture data as a PNG.
// Take notice of lines 26 and 27. You only need to initialize
// the QOI plugin (this registers the function hooks that Allegro
// will use whenever you want to I/O on a filename ending in .qoi)
// 
// Compile the sample program with:
// gcc -o sample allegro_qoi.c sample.c -lallegro -lallegro_image -I./
// Then run it with a QOI image as the first argument.
// 
// qoi.h should be inside of your include path.
// Either place it here, or in your system's global includes.
