public class AntiAliasingCommand : RasterCommand

@interface LTAntiAliasingCommand : LTRasterCommand

public class AntiAliasingCommand

class AntiAliasingCommand(RasterCommand):

Remarks

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.

Example

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

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void AntiAliasingCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Jagged.jpg")); 
 
   // Prepare the command 
   AntiAliasingCommand command = new AntiAliasingCommand(); 
   //do the anti-aliasing on the image. 
   command.Threshold = 25; 
   command.Dimension = 7; 
   command.Filter = AntiAliasingCommandType.Type1; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
