al_set_separate_blender — Allegro 5 API


#include <allegro5/allegro.h>

void al_set_separate_blender(int op, int src, int dst,
   int alpha_op, int alpha_src, int alpha_dst)


Like al_set_blender(3), but allows specifying a separate blending operation for the alpha channel. This is useful if your target bitmap also has an alpha channel and the two alpha channels need to be combined in a different way than the color components.
