BLEND_FACTOR_ONE	(1,1,1)	1
BLEND_FACTOR_SRC_COLOR	(Rs0,Gs0,Bs0)	As0
BLEND_FACTOR_ONE_MINUS_SRC_COLOR	(1-Rs0,1-Gs0,1-Bs0)	1-As0
BLEND_FACTOR_DST_COLOR	(Rd,Gd,Bd)	Ad
BLEND_FACTOR_ONE_MINUS_DST_COLOR	(1-Rd,1-Gd,1-Bd)	1-Ad
BLEND_FACTOR_SRC_ALPHA	(As0,As0,As0)	As0
BLEND_FACTOR_ONE_MINUS_SRC_ALPHA	(1-As0,1-As0,1-As0)	1-As0
BLEND_FACTOR_DST_ALPHA	(Ad,Ad,Ad)	Ad
BLEND_FACTOR_ONE_MINUS_DST_ALPHA	(1-Ad,1-Ad,1-Ad)	1-Ad
BLEND_FACTOR_CONSTANT_COLOR	(Rc,Gc,Bc)	Ac

BLEND_FACTOR_ONE_MINUS_CONSTANT_ALPHA	(1-Ac,1-Ac,1-Ac)	1-Ac
BLEND_FACTOR_SRC_ALPHA_SATURATE	(f,f,f); f = min(As0,1-Ad)	1
BLEND_FACTOR_SRC1_COLOR	(Rs1,Gs1,Bs1)	As1
BLEND_FACTOR_ONE_MINUS_SRC1_COLOR	(1-Rs1,1-Gs1,1-Bs1)	1-As1
BLEND_FACTOR_SRC1_ALPHA	(As1,As1,As1)	As1
BLEND_FACTOR_ONE_MINUS_SRC1_ALPHA	(1-As1,1-As1,1-As1)	1-As1

Blend Factors

In this table, the following conventions are used:

• Rs0,Gs0,Bs0 and As0 represent the first source color R, G, B, and A components, respectively, for the fragment output location corresponding to the color attachment being blended.
• Rs1,Gs1,Bs1 and As1 represent the second source color R, G, B, and A components, respectively, used in dual source blending modes, for the fragment output location corresponding to the color attachment being blended.
• Rd,Gd,Bd and Ad represent the R, G, B, and A components of the destination color. That is, the color currently in the corresponding color attachment for this fragment/sample.
• Rc,Gc,Bc and Ac represent the blend constant R, G, B, and A components, respectively.
