D2D1_BLEND enumeration (d2d1effectauthor.h)

  • Article

Specifies how one of the color sources is to be derived and optionally specifies a preblend operation on the color source.

} ;

Constants

 
D2D1_BLEND_ZERO
Value: 1
The data source is black (0, 0, 0, 0). There is no preblend operation.
D2D1_BLEND_ONE
Value: 2
The data source is white (1, 1, 1, 1). There is no preblend operation.
D2D1_BLEND_SRC_COLOR
Value: 3
The data source is color data (RGB) from the second input of the blend transform. There is not a preblend operation.
D2D1_BLEND_INV_SRC_COLOR
Value: 4
The data source is color data (RGB) from second input of the blend transform. The preblend operation inverts the data, generating 1 - RGB.
D2D1_BLEND_SRC_ALPHA
Value: 5
The data source is alpha data (A) from second input of the blend transform. There is no preblend operation.
D2D1_BLEND_INV_SRC_ALPHA
Value: 6
The data source is alpha data (A) from the second input of the blend transform. The preblend operation inverts the data, generating 1 - A.
D2D1_BLEND_DEST_ALPHA
Value: 7
The data source is alpha data (A) from the first input of the blend transform. There is no preblend operation.
D2D1_BLEND_INV_DEST_ALPHA
Value: 8
The data source is alpha data (A) from the first input of the blend transform. The preblend operation inverts the data, generating 1 - A.
D2D1_BLEND_DEST_COLOR
Value: 9
The data source is color data from the first input of the blend transform. There is no preblend operation.
D2D1_BLEND_INV_DEST_COLOR
Value: 10
The data source is color data from the first input of the blend transform. The preblend operation inverts the data, generating 1 - RGB.
D2D1_BLEND_SRC_ALPHA_SAT
Value: 11
The data source is alpha data from the second input of the blend transform. The preblend operation clamps the data to 1 or less.
D2D1_BLEND_BLEND_FACTOR
Value: 14
The data source is the blend factor. There is no preblend operation.
D2D1_BLEND_INV_BLEND_FACTOR
Value: 15
The data source is the blend factor. The preblend operation inverts the blend factor, generating 1 - blend_factor.
D2D1_BLEND_FORCE_DWORD
Value: 0xffffffff

Remarks

This enumeration has the same numeric values as D3D10_BLEND.
