SDL Blending Modes

Members

SDL_BlendMode alias SDL_BlendMode = Uint32: A set of blend modes used in drawing operations.

SDL_BlendFactor enum SDL_BlendFactor: The normalized factor used to multiply pixel components.
SDL_BlendOperation enum SDL_BlendOperation: The blend operation used when combining source and destination pixel components.

SDL_ComposeCustomBlendMode SDL_BlendMode SDL_ComposeCustomBlendMode(SDL_BlendFactor srcColorFactor, SDL_BlendFactor dstColorFactor, SDL_BlendOperation colorOperation, SDL_BlendFactor srcAlphaFactor, SDL_BlendFactor dstAlphaFactor, SDL_BlendOperation alphaOperation): Compose a custom blend mode for renderers.

SDL_BLENDMODE_ADD enum SDL_BlendMode SDL_BLENDMODE_ADD;: additive blending: dstRGB = (srcRGB * srcA) + dstRGB, dstA = dstA
SDL_BLENDMODE_ADD_PREMULTIPLIED enum SDL_BlendMode SDL_BLENDMODE_ADD_PREMULTIPLIED;: pre-multiplied additive blending: dstRGB = srcRGB + dstRGB, dstA = dstA
SDL_BLENDMODE_BLEND enum SDL_BlendMode SDL_BLENDMODE_BLEND;: alpha blending: dstRGB = (srcRGB * srcA) + (dstRGB * (1-srcA)), dstA = srcA + (dstA * (1-srcA))
SDL_BLENDMODE_BLEND_PREMULTIPLIED enum SDL_BlendMode SDL_BLENDMODE_BLEND_PREMULTIPLIED;: pre-multiplied alpha blending: dstRGBA = srcRGBA + (dstRGBA * (1-srcA))
SDL_BLENDMODE_INVALID enum SDL_BlendMode SDL_BLENDMODE_INVALID;: Undocumented in source but is binding to C. You might be able to learn more by searching the web for its name.
SDL_BLENDMODE_MOD enum SDL_BlendMode SDL_BLENDMODE_MOD;: color modulate: dstRGB = srcRGB * dstRGB, dstA = dstA
SDL_BLENDMODE_MUL enum SDL_BlendMode SDL_BLENDMODE_MUL;: color multiply: dstRGB = (srcRGB * dstRGB) + (dstRGB * (1-srcA)), dstA = dstA
SDL_BLENDMODE_NONE enum SDL_BlendMode SDL_BLENDMODE_NONE;: no blending: dstRGBA = srcRGBA
