D3D10_DDI_BLEND_DESC structure

Description

The D3D10_DDI_BLEND_DESC structure describes a blend state.

Members

AlphaToCoverageEnable [in]

A Boolean value that specifies whether transparency coverage is enabled. TRUE indicates transparency coverage is enabled; FALSE indicates transparency coverage is disabled. This member is relevant for multiple-sample antialiasing only.

BlendEnable [in]

An array of Boolean values that specify whether blending is enabled for each associated render target. TRUE indicates blending is enabled; FALSE indicates blending is disabled.

SrcBlend [in]

A D3D10_DDI_BLEND-typed value that indicates the blend mode of the source for all enabled render targets.

DestBlend [in]

A D3D10_DDI_BLEND-typed value that indicates the blend mode of the destination for all enabled render targets.

BlendOp [in]

A D3D10_DDI_BLEND_OP-typed value that indicates the blending operation for all enabled render targets.

SrcBlendAlpha [in]

A D3D10_DDI_BLEND-typed value that indicates the transparency blend mode of the source for all enabled render targets.

DestBlendAlpha [in]

A D3D10_DDI_BLEND-typed value that indicates the transparency blend mode of the destination for all enabled render targets.

BlendOpAlpha [in]

A D3D10_DDI_BLEND_OP-typed value that indicates the transparency blending operation for all enabled render targets.

RenderTargetWriteMask [in]

An array of 8-bit bitwise values that indicate the write properties for each associated render target. Each bit of each element must be set to one of the following values from the D3D10_DDI_COLOR_WRITE_ENABLE enumeration.

Value Meaning
D3D10_DDI_COLOR_WRITE_ENABLE_RED (1) Writes red
D3D10_DDI_COLOR_WRITE_ENABLE_GREEN (2) Writes green
D3D10_DDI_COLOR_WRITE_ENABLE_BLUE (4) Writes blue
D3D10_DDI_COLOR_WRITE_ENABLE_ALPHA (8) Writes a transparency level
D3D10_DDI_COLOR_WRITE_ENABLE_ALL (bitwise OR of 1,2,4,8) Writes red, green, blue, and a transparency level
