Constants

D3D11_BLEND_ZERO Value: 1 The blend factor is (0, 0, 0, 0). No pre-blend operation.
D3D11_BLEND_ONE Value: 2 The blend factor is (1, 1, 1, 1). No pre-blend operation.
D3D11_BLEND_SRC_COLOR Value: 3 The blend factor is (Rₛ, Gₛ, Bₛ, Aₛ), that is color data (RGB) from a pixel shader. No pre-blend operation.
D3D11_BLEND_INV_SRC_COLOR Value: 4 The blend factor is (1 - Rₛ, 1 - Gₛ, 1 - Bₛ, 1 - Aₛ), that is color data (RGB) from a pixel shader. The pre-blend operation inverts the data, generating 1 - RGB.
D3D11_BLEND_SRC_ALPHA Value: 5 The blend factor is (Aₛ, Aₛ, Aₛ, Aₛ), that is alpha data (A) from a pixel shader. No pre-blend operation.
D3D11_BLEND_INV_SRC_ALPHA Value: 6 The blend factor is ( 1 - Aₛ, 1 - Aₛ, 1 - Aₛ, 1 - Aₛ), that is alpha data (A) from a pixel shader. The pre-blend operation inverts the data, generating 1 - A.
D3D11_BLEND_DEST_ALPHA Value: 7 The blend factor is (Ad Ad Ad Ad), that is alpha data from a render target. No pre-blend operation.
D3D11_BLEND_INV_DEST_ALPHA Value: 8 The blend factor is (1 - Ad 1 - Ad 1 - Ad 1 - Ad), that is alpha data from a render target. The pre-blend operation inverts the data, generating 1 - A.
D3D11_BLEND_DEST_COLOR Value: 9 The blend factor is (Rd, Gd, Bd, Ad), that is color data from a render target. No pre-blend operation.
D3D11_BLEND_INV_DEST_COLOR Value: 10 The blend factor is (1 - Rd, 1 - Gd, 1 - Bd, 1 - Ad), that is color data from a render target. The pre-blend operation inverts the data, generating 1 - RGB.
D3D11_BLEND_SRC_ALPHA_SAT Value: 11 The blend factor is (f, f, f, 1); where f = min(Aₛ, 1 - Ad). The pre-blend operation clamps the data to 1 or less.
D3D11_BLEND_BLEND_FACTOR Value: 14 The blend factor is the blend factor set with ID3D11DeviceContext::OMSetBlendState. No pre-blend operation.
D3D11_BLEND_INV_BLEND_FACTOR Value: 15 The blend factor is the blend factor set with ID3D11DeviceContext::OMSetBlendState. The pre-blend operation inverts the blend factor, generating 1 - blend_factor.
D3D11_BLEND_SRC1_COLOR Value: 16 The blend factor is data sources both as color data output by a pixel shader. There is no pre-blend operation. This blend factor supports dual-source color blending.
D3D11_BLEND_INV_SRC1_COLOR Value: 17 The blend factor is data sources both as color data output by a pixel shader. The pre-blend operation inverts the data, generating 1 - RGB. This blend factor supports dual-source color blending.
D3D11_BLEND_SRC1_ALPHA Value: 18 The blend factor is data sources as alpha data output by a pixel shader. There is no pre-blend operation. This blend factor supports dual-source color blending.
D3D11_BLEND_INV_SRC1_ALPHA Value: 19 The blend factor is data sources as alpha data output by a pixel shader. The pre-blend operation inverts the data, generating 1 - A. This blend factor supports dual-source color blending.

Remarks

Blend operations are specified in a blend description.
