Example

Run the AlphaBlendCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void SourcePointPropertyExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   RasterImage srcImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image3.cmp"), 24, CodecsLoadByteOrder.Bgr, 1, 1); 
 
   AlphaBlendCommand command = new AlphaBlendCommand(); 
   // Combine srcImage with image, with half opacity. 
   //command.DestinationRectangle = new LeadRect(image.Width / 2 - srcImage.Width / 2, image.Height / 2 - srcImage.Height / 2, image.Width / 2 + srcImage.Width / 8, image.Height / 2 + srcImage.Height / 8); 
   command.DestinationRectangle = new LeadRect(image.Width / 8, image.Height / 8, image.Width, image.Height); 
   command.SourceImage = srcImage; 
   command.SourcePoint = new LeadPoint(0, 0); 
   command.Opacity = 128; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
