CRset_blend_mode | R Documentation |
Sets the blend mode when using render drawing operations (CRfill_rect
etc.). The blend mode affects how colors at the same screen position are combined during rendering, based on their alpha value. Mode "none" simply overwrites color. Mode "blend" does alpha blending, with resulting color a weighted average of rendered colors. Mode "add" does additive blending, mode "mod" does color modulation.
