Field Value

Type	Description
UnsharpMaskSettings

Properties

Amount

The amount of sharpening. This value represents a percentage of the difference between the blurred image and the original image.

Declaration

public int Amount { get; }

Property Value

Type	Description
System.Int32	Typical values are between 25 and 200.

Radius

The radius (sigma) of the gaussian blur used for the mask. This value determines the size of details that are sharpened.

Declaration

public double Radius { get; }

Property Value

Type	Description
System.Double	Typical values are between 0.3 and 3.0. Larger radius values can have significant performance cost.

Threshold

The minimum brightness change required for a pixel to be modified by the filter.

Declaration

public byte Threshold { get; }

Property Value

Type	Description
System.Byte	Typical values are between 0 and 10.

Remarks

When using larger Radius or Amount values, a larger Threshold value can ensure lines are sharpened while textures are not.
