LinearGradientBrush::SetGammaCorrection method (gdiplusbrush.h)
The LinearGradientBrush::SetGammaCorrection method specifies whether gamma correction is enabled for this linear gradient brush.
Syntax
Status SetGammaCorrection(
[in] BOOL useGammaCorrection
);
Parameters
[in] useGammaCorrection
Type: BOOL
Boolean value that specifies whether gamma correction occurs during rendering. TRUE specifies that gamma correction is enabled, and FALSE specifies that gamma correction is not enabled. By default, gamma correction is disabled during construction of a LinearGradientBrush object.
Return value
Type: Status
If the method succeeds, it returns Ok, which is an element of the Status enumeration.
If the method fails, it returns one of the other elements of the Status enumeration.
Remarks
Gamma correction is often done to match the intensity contrast of the gradient to the ability of the human eye to perceive intensity changes.
