Constants

D3D10_BLEND_ZERO

The data source is the color black (0, 0, 0, 0). No pre-blend operation.

D3D10_BLEND_ONE

The data source is the color white (1, 1, 1, 1). No pre-blend operation.

D3D10_BLEND_SRC_COLOR

The data source is color data (RGB) from a pixel shader. No pre-blend operation.

D3D10_BLEND_INV_SRC_COLOR

The data source is color data (RGB) from a pixel shader. The pre-blend operation inverts the data, generating 1 - RGB.

D3D10_BLEND_SRC_ALPHA

The data source is alpha data (A) from a pixel shader. No pre-blend operation.

D3D10_BLEND_INV_SRC_ALPHA

The data source is alpha data (A) from a pixel shader. The pre-blend operation inverts the data, generating 1 - A.

D3D10_BLEND_DEST_ALPHA

The data source is alpha data from a rendertarget. No pre-blend operation.

D3D10_BLEND_INV_DEST_ALPHA

The data source is alpha data from a rendertarget. The pre-blend operation inverts the data, generating 1 - A.

D3D10_BLEND_DEST_COLOR

The data source is color data from a rendertarget. No pre-blend operation.

D3D10_BLEND_INV_DEST_COLOR

The data source is color data from a rendertarget. The pre-blend operation inverts the data, generating 1 - RGB.

D3D10_BLEND_SRC_ALPHA_SAT

The data source is alpha data from a pixel shader. The pre-blend operation clamps the data to 1 or less.

D3D10_BLEND_BLEND_FACTOR

The data source is the blend factor set with ID3D10Device::OMSetBlendState. No pre-blend operation.

D3D10_BLEND_INV_BLEND_FACTOR

The data source is the blend factor set with ID3D10Device::OMSetBlendState. The pre-blend operation inverts the blend factor, generating 1 - blend_factor.

D3D10_BLEND_SRC1_COLOR

The data sources are both color data output by a pixel shader. There is no pre-blend operation. This options supports dual-source color blending.

D3D10_BLEND_INV_SRC1_COLOR

The data sources are both color data output by a pixel shader. The pre-blend operation inverts the data, generating 1 - RGB. This options supports dual-source color blending.

D3D10_BLEND_SRC1_ALPHA

The data sources are alpha data output by a pixel shader. There is no pre-blend operation. This options supports dual-source color blending.

D3D10_BLEND_INV_SRC1_ALPHA

The data sources are alpha data output by a pixel shader. The pre-blend operation inverts the data, generating 1 - A. This options supports dual-source color blending.

Remarks

Blend operations are specified in a blend description.
