\brief The blend mode used in SDL_RenderCopy() and drawing operations.

Variants

SDL_BLENDMODE_NONE

< no blending dstRGBA = srcRGBA

SDL_BLENDMODE_BLEND

< alpha blending dstRGB = (srcRGB * srcA) + (dstRGB * (1-srcA)) dstA = srcA + (dstA * (1-srcA))

SDL_BLENDMODE_ADD

< additive blending dstRGB = (srcRGB * srcA) + dstRGB dstA = dstA

SDL_BLENDMODE_MOD

< color modulate dstRGB = srcRGB * dstRGB dstA = dstA

SDL_BLENDMODE_MUL

< color multiply dstRGB = (srcRGB * dstRGB) + (dstRGB * (1-srcA)) dstA = (srcA * dstA) + (dstA * (1-srcA))

SDL_BLENDMODE_INVALID
