[SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_BlendOperation The blend operation used when combining source and destination pixel components. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_blendmode.h) ## Syntax ```c typedef enum SDL_BlendOperation { SDL_BLENDOPERATION_ADD = 0x1, /**< dst + src: supported by all renderers */ SDL_BLENDOPERATION_SUBTRACT = 0x2, /**< src - dst : supported by D3D9, D3D11, OpenGL, OpenGLES */ SDL_BLENDOPERATION_REV_SUBTRACT = 0x3, /**< dst - src : supported by D3D9, D3D11, OpenGL, OpenGLES */ SDL_BLENDOPERATION_MINIMUM = 0x4, /**< min(dst, src) : supported by D3D9, D3D11 */ SDL_BLENDOPERATION_MAXIMUM = 0x5 /**< max(dst, src) : supported by D3D9, D3D11 */ } SDL_BlendOperation; ``` ## Version This enum is available since SDL 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIEnum](CategoryAPIEnum)
