Constants

 
D2D1_GAMMATRANSFER_PROP_RED_AMPLITUDE
Value: 0
The amplitude of the gamma transfer function for the Red channel.


The type is FLOAT.

The default value is 1.0f.
D2D1_GAMMATRANSFER_PROP_RED_EXPONENT
Value: 1
The exponent of the gamma transfer function for the Red channel.


The type is FLOAT.

The default value is 1.0f.
D2D1_GAMMATRANSFER_PROP_RED_OFFSET
Value: 2
The offset of the gamma transfer function for the Red channel.


The type is FLOAT.

The default value is 0.0f.
D2D1_GAMMATRANSFER_PROP_RED_DISABLE
Value: 3
If you set this to TRUE it does not apply the transfer function to the Red channel. An identity transfer function is used.
If you set this to FALSE it applies the gamma transfer function to the Red channel.


The type is BOOL.

The default value is FALSE.
D2D1_GAMMATRANSFER_PROP_GREEN_AMPLITUDE
Value: 4
The amplitude of the gamma transfer function for the Green channel.


The type is FLOAT.

The default value is 1.0f.
D2D1_GAMMATRANSFER_PROP_GREEN_EXPONENT
Value: 5
The exponent of the gamma transfer function for the Green channel.


The type is FLOAT.

The default value is 1.0f.
D2D1_GAMMATRANSFER_PROP_GREEN_OFFSET
Value: 6
The offset of the gamma transfer function for the Green channel.


The type is FLOAT.

The default value is 0.0f.
D2D1_GAMMATRANSFER_PROP_GREEN_DISABLE
Value: 7
If you set this to TRUE it does not apply the transfer function to the Green channel. An identity transfer function is used.
If you set this to FALSE it applies the gamma transfer function to the Green channel.


The type is BOOL.

The default value is FALSE.
D2D1_GAMMATRANSFER_PROP_BLUE_AMPLITUDE
Value: 8
The amplitude of the gamma transfer function for the Blue channel.


The type is FLOAT.

The default value is 1.0f.
D2D1_GAMMATRANSFER_PROP_BLUE_EXPONENT
Value: 9
The exponent of the gamma transfer function for the Blue channel.


The type is FLOAT.

The default value is 1.0f.
D2D1_GAMMATRANSFER_PROP_BLUE_OFFSET
Value: 10
The offset of the gamma transfer function for the Blue channel.


The type is FLOAT.

The default value is 0.0f.
D2D1_GAMMATRANSFER_PROP_BLUE_DISABLE
Value: 11
If you set this to TRUE it does not apply the transfer function to the Blue channel. An identity transfer function is used.
If you set this to FALSE it applies the gamma transfer function to the Blue channel.


The type is BOOL.

The default value is FALSE.
D2D1_GAMMATRANSFER_PROP_ALPHA_AMPLITUDE
Value: 12
The amplitude of the gamma transfer function for the Alpha channel.


The type is FLOAT.

The default value is 1.0f.
D2D1_GAMMATRANSFER_PROP_ALPHA_EXPONENT
Value: 13
The exponent of the gamma transfer function for the Alpha channel.


The type is FLOAT.

The default value is 1.0f.
D2D1_GAMMATRANSFER_PROP_ALPHA_OFFSET
Value: 14
The offset of the gamma transfer function for the Alpha channel.


The type is FLOAT.

The default value is 0.0f.
D2D1_GAMMATRANSFER_PROP_ALPHA_DISABLE
Value: 15
If you set this to TRUE it does not apply the transfer function to the Alpha channel. An identity transfer function is used.
If you set this to FALSE it applies the gamma transfer function to the Alpha channel.


The type is BOOL.

The default value is FALSE.
D2D1_GAMMATRANSFER_PROP_CLAMP_OUTPUT
Value: 16
Whether the effect clamps color values to between 0 and 1 before the effect passes the values to the next effect in the graph.
The effect clamps the values before it premultiplies the alpha.


If you set this to TRUE the effect will clamp the values. If you set this to FALSE, the effect will not clamp the color values,
but other effects and the output surface may clamp the values if they are not of high enough precision.


The type is BOOL.

The default value is FALSE.
D2D1_GAMMATRANSFER_PROP_FORCE_DWORD
Value: 0xffffffff
