Leadtools.ImageProcessing.Effects Namespace > AntiAliasingCommand Class > AntiAliasingCommand Constructor : AntiAliasingCommand Constructor(Int32,Int32,AntiAliasingCommandType)



threshold
Threshold value that indicates which pixels to smooth. The application of the anti-aliasing filter on the image associates a value with each pixel. Only pixels with values above this threshold are smoothed. This parameter only accepts positive values.
dimension
Value that indicates the size of the anti-aliasing mask. For example, a value of three indicates an anti-aliasing mask of 3 X 3. This parameter only accepts positive values.
filter
Flag that indicates the type of anti-aliasing filter to use.
Initializes a new AntiAliasingCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7

Parameters

threshold
Threshold value that indicates which pixels to smooth. The application of the anti-aliasing filter on the image associates a value with each pixel. Only pixels with values above this threshold are smoothed. This parameter only accepts positive values.
dimension
Value that indicates the size of the anti-aliasing mask. For example, a value of three indicates an anti-aliasing mask of 3 X 3. This parameter only accepts positive values.
filter
Flag that indicates the type of anti-aliasing filter to use.

Example

Run the AntiAliasingCommand on an image and does anti-aliasing on it.
