= SDL_BlendFactor =
An enumeration of blend factors used when creating a custom blend mode with [[SDL_ComposeCustomBlendMode]]().

<<TableOfContents()>>

== Values ==
||SDL_BLENDFACTOR_ZERO||0, 0, 0, 0||
||SDL_BLENDFACTOR_ONE||1, 1, 1, 1||
||SDL_BLENDFACTOR_SRC_COLOR||srcR, srcG, srcB, srcA||
||SDL_BLENDFACTOR_ONE_MINUS_SRC_COLOR||1-srcR, 1-srcG, 1-srcB, 1-srcA||
||SDL_BLENDFACTOR_SRC_ALPHA||srcA, srcA, srcA, srcA||
||SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA||1-srcA, 1-srcA, 1-srcA, 1-srcA||
||SDL_BLENDFACTOR_DST_COLOR||dstR, dstG, dstB, dstA||
||SDL_BLENDFACTOR_ONE_MINUS_DST_COLOR||1-dstR, 1-dstG, 1-dstB, 1-dstA||
||SDL_BLENDFACTOR_DST_ALPHA||dstA, dstA, dstA, dstA||
||SDL_BLENDFACTOR_ONE_MINUS_DST_ALPHA||1-dstA, 1-dstA, 1-dstA, 1-dstA||

== Remarks ==

The blend factors are multiplied with the pixels from a drawing operation (src) and the pixels from the render target (dst) before the blend operation. The comma-separated factors listed above are always applied in the component order red, green, blue, and alpha.

Some renderers may not support all factors. See [[SDL_ComposeCustomBlendMode]]() for a list of what the current renderers support.

== Version ==

This enumeration is available since SDL 2.0.6.
