'Declaration
 
Public Class AntiAliasingCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As AntiAliasingCommand

public ref class AntiAliasingCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

The best results for anti-aliasing text can be obtained with the filter AntiAliasingCommandType.Type2.
The value of the Dimension property determines the extent of the anti-aliasing.
The threshold range for 16, 48 and 64-bit images is from 0 to 65535 and for 12-bit images the threshold range is from 0 to 4095. Otherwise, it is from 0 to 255. The threshold is applied on channels separately.
This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. And can process the whole image or a region of the image. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support 32-bit grayscale images.
