NAME

       SDL_BlendMode - A set of blend modes used in drawing operations.

SYNOPSIS

       #include <SDL3/SDL_blendmode.h>

       typedef Uint32 SDL_BlendMode;

       #define SDL_BLENDMODE_NONE                  0x00000000u /**< no blending: dstRGBA = srcRGBA */
       #define SDL_BLENDMODE_BLEND                 0x00000001u /**< alpha blending: dstRGB = (srcRGB * srcA) + (dstRGB * (1-srcA)), dstA = srcA + (dstA * (1-srcA)) */
       #define SDL_BLENDMODE_BLEND_PREMULTIPLIED   0x00000010u /**< pre-multiplied alpha blending: dstRGBA = srcRGBA + (dstRGBA * (1-srcA)) */
       #define SDL_BLENDMODE_ADD                   0x00000002u /**< additive blending: dstRGB = (srcRGB * srcA) + dstRGB, dstA = dstA */
       #define SDL_BLENDMODE_ADD_PREMULTIPLIED     0x00000020u /**< pre-multiplied additive blending: dstRGB = srcRGB + dstRGB, dstA = dstA */
       #define SDL_BLENDMODE_MOD                   0x00000004u /**< color modulate: dstRGB = srcRGB * dstRGB, dstA = dstA */
       #define SDL_BLENDMODE_MUL                   0x00000008u /**< color multiply: dstRGB = (srcRGB * dstRGB) + (dstRGB * (1-srcA)), dstA = dstA */
       #define SDL_BLENDMODE_INVALID               0x7FFFFFFFu

DESCRIPTION

       These predefined blend modes are supported everywhere.

       Additional values may be obtained from SDL_ComposeCustomBlendMode.

AVAILABILITY

       This datatype is available since SDL 3.2.0.
