UnsharpMask Constructor (Single, Single, Single)

Creates and initializes new UnsharpMask class instance. You can set all three unsharp mask main values here.

Namespace: Aurigma.GraphicsMill.Transforms
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

Syntax

Visual Basic

Public Sub New ( _
	amount As Single, _
	radius As Single, _
	threshold As Single _
)

C#

public UnsharpMask(
	float amount,
	float radius,
	float threshold
)

Parameters

amount: Type: System.Single
Value that specifies unsharp mask amount. Amount*100 means the percentage of the difference between blurred and original image. Min value is 0. You can change it later using Amount property.

radius: Type: System.Single
Value that specifies blur radius used to produce unfocused version of the image. You can change it later using Radius property.

threshold: Type: System.Single
Value in range [0, 1] specifying threshold value for the unsharp mask. Minimum value (0) means that all pixels are affected with unsharp mask, maximum value means that no pixels are affected. To calculate threshold in pixel luminosity levels, multiply it on 255 for non-extended (8 bit per channel) images, or 65535 for extended (16 bit per channel) images. You can change it later using Threshold property.
