CreateBrightnessFilter(float)

Create a brightness filter matrix using the given amount.

Declaration

public static ColorMatrix CreateBrightnessFilter(float amount)

Parameters

Type	Name	Description
float	amount	The proportion of the conversion. Must be greater than or equal to 0.

Returns

Type	Description
ColorMatrix	The ColorMatrix

Remarks

A value of 0 will create an image that is completely black. A value of 1 leaves the input unchanged. Other values are linear multipliers on the effect. Values of an amount over 1 are allowed, providing brighter results.

CreateContrastFilter(float)

Create a contrast filter matrix using the given amount.

Declaration

public static ColorMatrix CreateContrastFilter(float amount)

Parameters

Type	Name	Description
float	amount	The proportion of the conversion. Must be greater than or equal to 0.

Returns

Type	Description
ColorMatrix	The ColorMatrix

Remarks

A value of 0 will create an image that is completely gray. A value of 1 leaves the input unchanged. Other values are linear multipliers on the effect. Values of an amount over 1 are allowed, providing results with more contrast.
