# al\_set\_separate\_bitmap\_blender(3)

Allegro 5 API

## NAME

al\_set\_separate\_bitmap\_blender - Allegro 5 API

  #include <allegro5/allegro.h>
  void al_set_separate_bitmap_blender(int op, int src, int dst, int alpha_op, int alpha_src, int alpha_dst)
  ```

## DESCRIPTION

Like [al\_set\_bitmap\_blender(3)](/al_set_bitmap_blender/3.md), 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.
