Syntax

C++/CLI

Python

public class ZoomBlurCommand : RasterCommand

public ref class ZoomBlurCommand : public RasterCommand

class ZoomBlurCommand(RasterCommand):

Remarks

The command will blur and zoom the image around the specified center point. The center point must be defined inside the image, or inside the region if the image has a region.
If the image has a region, the effect will be applied on the region only.
This command supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support signed data images.
This command does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this method.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void ZoomBlurCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   ZoomBlurCommand command = new ZoomBlurCommand(); 
   command.CenterPoint = new LeadPoint((image.Width / 2), (image.Height / 2)); 
   command.Dimension = 50; 
   command.Stress = 5; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
