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
Enable (or disable) blending.

LogicOpEnable
Enable (or disable) a logical operation.

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

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

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

RenderTargetWriteMask
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.

Requirements

Header: Declared in d3d11_x.h (d3d11_1.h on other Windows platforms).

Library: Use d3d11_x.lib (d3d11.lib on other Windows platforms).
