AdjustLevels Method

AdjustLevels(Color, Color, Color, Color, float)

Adjusts the levels of an image histogram.

The method maps the input range of values (blackPoint..whitePoint) to the output range (outputBlack..outputWhite) using the specified gamma correction (midtone).

Declaration

public void AdjustLevels(Color blackPoint, Color whitePoint, Color outputBlack, Color outputWhite, float midtone = 1)

Parameters

Type	Name	Description
Color	blackPoint
Color	whitePoint
Color	outputBlack
Color	outputWhite
float	midtone

AdjustLevels(uint, uint, uint, uint, float)

Adjusts the levels of an image histogram.

The method maps the input range of values (blackPoint..whitePoint) to the output range (outputBlack..outputWhite) using the specified gamma correction (midtone).

Declaration

public void AdjustLevels(uint blackPoint, uint whitePoint, uint outputBlack, uint outputWhite, float midtone = 1)

Parameters

Type	Name	Description
uint	blackPoint	The input black point in 32-bit ARGB format (the Alpha channel is ignored).
uint	whitePoint	The input white point in 32-bit ARGB format (the Alpha channel is ignored).
uint	outputBlack	The output black point in 32-bit ARGB format (the Alpha channel is ignored).
uint	outputWhite	The output white point in 32-bit ARGB format (the Alpha channel is ignored).
float	midtone	The value of gamma correction.
