sdlSetSurfaceBlendMode function

int sdlSetSurfaceBlendMode(Pointer<SdlSurface> surface, int blendMode)

Set the blend mode used for blit operations.

To copy a surface to another surface (or texture) without blending with the existing data, the blendmode of the SOURCE surface should be set to SDL_BLENDMODE_NONE.

\param surface the SDL_Surface structure to update \param blendMode the SDL_BlendMode to use for blit blending \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
