D3D11_RENDER_TARGET_BLEND_DESC1 structure

Note  This structure is supported by the Direct3D 11.1 runtime, which is available on Windows 8 and later operating systems.

Describes the blend state for a render target.

Syntax


typedef struct _D3D11_RENDER_TARGET_BLEND_DESC1 {
  BOOL           BlendEnable;
  BOOL           LogicOpEnable;
  D3D11_BLEND    SrcBlend;
  D3D11_BLEND    DestBlend;
  D3D11_BLEND_OP BlendOp;
  D3D11_BLEND    SrcBlendAlpha;
  D3D11_BLEND    DestBlendAlpha;
  D3D11_BLEND_OP BlendOpAlpha;
  D3D11_LOGIC_OP LogicOp;
  UINT8          RenderTargetWriteMask;
} D3D11_RENDER_TARGET_BLEND_DESC1;

Members

BlendEnable

Type: BOOL

Enable (or disable) blending.

LogicOpEnable

Type: BOOL

Enable (or disable) a logical operation.

SrcBlend

Type: D3D11_BLEND

This blend option specifies the operation to perform on the RGB value that the pixel shader outputs. The BlendOp member defines how to combine the SrcBlend and DestBlend operations.

DestBlend

Type: D3D11_BLEND

This blend option specifies the operation to perform on the current RGB value in the render target. The BlendOp member defines how to combine the SrcBlend and DestBlend operations.

BlendOp

Type: D3D11_BLEND_OP

This blend operation defines how to combine the SrcBlend and DestBlend operations.

SrcBlendAlpha

Type: D3D11_BLEND

This blend option specifies the operation to perform on the alpha value that the pixel shader outputs. Blend options that end in _COLOR are not allowed. The BlendOpAlpha member defines how to combine the SrcBlendAlpha and DestBlendAlpha operations.

DestBlendAlpha

Type: D3D11_BLEND

This blend option specifies the operation to perform on the current alpha value in the render target. Blend options that end in _COLOR are not allowed. The BlendOpAlpha member defines how to combine the SrcBlendAlpha and DestBlendAlpha operations.

BlendOpAlpha

Type: D3D11_BLEND_OP

This blend operation defines how to combine the SrcBlendAlpha and DestBlendAlpha operations.

LogicOp

Type: D3D11_LOGIC_OP

A D3D11_LOGIC_OP-typed value that specifies the logical operation to configure for the render target.

RenderTargetWriteMask

Type: UINT8

A write mask.

Remarks

You specify an array of D3D11_RENDER_TARGET_BLEND_DESC1 structures in the RenderTarget member of the D3D11_BLEND_DESC1 structure to describe the blend states for render targets; you can bind up to eight render targets to the output-merger stage at one time.

For info about how blending is done, see the output-merger stage.

Here are the default values for blend state.
