A blend operation is the act of executing the blending of a graphic (source) with the pixels the graphic is drawn on (target) using a blend table.

This is done in two ways:

  • The blendop is performed explicitly using blendop_apply(), modifying the graphic.
  • The blendop is assigned to a graphic and performed implicitly when that graphic is drawn. This method is not available for modes lower than 16bit.

Blendops are not supported in 32bit mode.
