Specifies the operator to be used when pixels in a render target are blended with existing pixels in the texture.

Header File

Syntax

typedef enum SDL_GPUBlendOp
{
    SDL_GPU_BLENDOP_INVALID,
    SDL_GPU_BLENDOP_ADD,               /**< (source * source_factor) + (destination * destination_factor) */
    SDL_GPU_BLENDOP_SUBTRACT,          /**< (source * source_factor) - (destination * destination_factor) */
    SDL_GPU_BLENDOP_REVERSE_SUBTRACT,  /**< (destination * destination_factor) - (source * source_factor) */
    SDL_GPU_BLENDOP_MIN,               /**< min(source, destination) */
    SDL_GPU_BLENDOP_MAX                /**< max(source, destination) */
} SDL_GPUBlendOp;

Remarks

The source color is the value written by the fragment shader. The destination color is the value currently existing in the texture.
