TransformsProvider.UnsharpMask Method (Single, Single, Single, BlurType)

Enhances image sharpness using unsharp mask technique.

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

Syntax

Visual Basic

Public Sub UnsharpMask ( _
        amount As Single, _
        radius As Single, _
        threshold As Single, _
        blurType As BlurType _
)

C#

public void UnsharpMask(
        float amount,
        float radius,
        float threshold,
        BlurType blurType
)

Parameters

amount: Type: System.Single
Value that specifies unsharp mask amount.

radius: Type: System.Single
Value that specifies blur radius used to produce unfocused version of the image.

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.

blurType: Type: Aurigma.GraphicsMill.Transforms.BlurType
BlurType value specifying a blur type used to produce unfocused version of the image.

Remarks

You can also use UnsharpMask class to apply this effect.
