No pre-blend operation. | | D3D12\_BLEND\_ONE | The blend factor is (1, 1, 1, 1). No pre-blend operation. | | D3D12\_BLEND\_SRC\_COLOR | The blend factor is (Rₛ, Gₛ, Bₛ, Aₛ), that is color data (RGB) from a pixel shader. No pre-blend operation. | | D3D12\_BLEND\_INV\_SRC\_COLOR | 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. | | D3D12\_BLEND\_SRC\_ALPHA | The blend factor is (Aₛ, Aₛ, Aₛ, Aₛ), that is alpha data (A) from a pixel shader. No pre-blend operation. | | D3D12\_BLEND\_INV\_SRC\_ALPHA | 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. | | D3D12\_BLEND\_DEST\_ALPHA | The blend factor is (Ad Ad Ad Ad), that is alpha data from a render target. No pre-blend operation. | | D3D12\_BLEND\_INV\_DEST\_ALPHA | 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. | | D3D12\_BLEND\_DEST\_COLOR | The blend factor is (Rd, Gd, Bd, Ad), that is color data from a render target. No pre-blend operation. | | D3D12\_BLEND\_INV\_DEST\_COLOR | 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. | | D3D12\_BLEND\_SRC\_ALPHA\_SAT | 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. | | D3D12\_BLEND\_BLEND\_FACTOR | The blend factor is the blend factor set with [ID3D12GraphicsCommandList::OMSetBlendFactor](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_omsetblendfactor_public). No pre-blend operation. | | D3D12\_BLEND\_INV\_BLEND\_FACTOR | The blend factor is the blend factor set with [ID3D12GraphicsCommandList::OMSetBlendFactor](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_omsetblendfactor_public). The pre-blend operation inverts the blend factor, generating 1 - blend\_factor. | | D3D12\_BLEND\_SRC1\_COLOR | 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. | | D3D12\_BLEND\_INV\_SRC1\_COLOR | 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. | | D3D12\_BLEND\_SRC1\_ALPHA | 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. | | D3D12\_BLEND\_INV\_SRC1\_ALPHA | 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. | | D3D12\_BLEND\_ALPHA\_FACTOR | The blend factor is (A, A, A, A), where the constant, A, is taken from the blend factor set with [OMSetBlendFactor](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_omsetblendfactor_public).
