Example

Runs the BinaryFilterCommand on an image to dilate black objects.

using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
public void BinaryFilterCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")); 
 
   // Prepare the command 
   BinaryFilterCommand command = new BinaryFilterCommand(BinaryFilterCommandPredefined.DilationOmniDirectional); 
   //Dilate black objects. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
