  BOOL           BlendEnable;
  D3D10_BLEND    SrcBlend;
  D3D10_BLEND    DestBlend;

} D3D10_RENDER_TARGET_BLEND_DESC1;

Members

BlendEnable

Type: BOOL

Enable (or disable) blending.

SrcBlend

Type: D3D10_BLEND

This blend option specifies the first RGB data source and includes an optional pre-blend operation.

DestBlend

Type: D3D10_BLEND

This blend option specifies the second RGB data source and includes an optional pre-blend operation.

BlendOp

Type: D3D10_BLEND_OP

This blend operation defines how to combine the RGB data sources.

SrcBlendAlpha

Type: D3D10_BLEND

This blend option specifies the first alpha data source and includes an optional pre-blend operation. Blend options that end in _COLOR are not allowed.

DestBlendAlpha

Type: D3D10_BLEND

This blend option specifies the second alpha data source and includes an optional pre-blend operation. Blend options that end in _COLOR are not allowed.

BlendOpAlpha

Type: D3D10_BLEND_OP

This blend operation defines how to combine the alpha data sources.

RenderTargetWriteMask

Type: UINT8

A write mask.

Remarks

To see how blending is done, see Output-Merger Stage (Direct3D 10).
