D2D1_CHROMAKEY_PROP enumeration (d2d1effects_2.h)

Identifiers for properties of the Chroma-key effect.

Syntax

typedef enum D2D1_CHROMAKEY_PROP {
  D2D1_CHROMAKEY_PROP_COLOR = 0,
  D2D1_CHROMAKEY_PROP_TOLERANCE = 1,
  D2D1_CHROMAKEY_PROP_INVERT_ALPHA = 2,
  D2D1_CHROMAKEY_PROP_FEATHER = 3,
  D2D1_CHROMAKEY_PROP_FORCE_DWORD = 0xffffffff
} ;

Constants

 
D2D1_CHROMAKEY_PROP_COLOR
Value: 0
The D2D1_CHROMAKEY_PROP_COLOR property is a vector4 value indicating the color that should be converted to alpha. The default color is black.
D2D1_CHROMAKEY_PROP_TOLERANCE
Value: 1
The D2D1_CHROMAKEY_PROP_TOLERANCE property is a float value indicating the tolerance for matching the color specified in the D2D1_CHROMAKEY_PROP_COLOR property.
The allowed range is 0.0 to 1.0. The default value is 0.1.
D2D1_CHROMAKEY_PROP_INVERT_ALPHA
Value: 2
The D2D1_CHROMAKEY_PROP_INVERT_ALPHA property is a boolean value indicating whether the alpha values should be inverted. The default value if False.
D2D1_CHROMAKEY_PROP_FEATHER
Value: 3
The D2D1_CHROMAKEY_PROP_FEATHER property is a boolean value whether the edges of the output should be softened in the alpha channel.
When set to False, the alpha output by the effect is 1-bit: either fully opaque or fully transparent. Setting to True results in a softening of edges in the alpha channel of the Chroma Key output.
The default value is False.
D2D1_CHROMAKEY_PROP_FORCE_DWORD
Value: 0xffffffff
