Applies an anti-aliasing filter to the specified image. This method is available in the Document/Medical Toolkits.
public class AntiAliasingCommand : RasterCommand 
Public Class AntiAliasingCommand  
   Inherits RasterCommand 
@interface LTAntiAliasingCommand : LTRasterCommand 
public class AntiAliasingCommand extends RasterCommand 
public ref class AntiAliasingCommand : public RasterCommand   
  • 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.

For more information, refer to Correcting Colors.
