CopyDataCommand Class

Summary

Copies image data from one image to another.

Syntax

Objective-C

C++

Java

public class CopyDataCommand : RasterCommand

Public Class CopyDataCommand  
   Inherits RasterCommand

@interface LTCopyDataCommand : LTRasterCommand

public class CopyDataCommand extends RasterCommand

public ref class CopyDataCommand : public RasterCommand

Remarks

The destination image must accurately identify the copied data. Therefore, the following properties must specify the same values for both the source and destination images:

The CopyDataCommand works by copying the image data from the image passed to the Run method to the image passed in the DestinationImage property.

Example

This example will use the CopyDataCommand to copy the image data from a source image to an existing image

public void CopyDataCommandExample()

   string destFileName = Path.Combine(ImagesPath.Path, "CopyDataCommand.bmp"); 
 
   // Load the source image from disk 
   RasterImage srcImage = codecs.Load(srcFileName); 
 
   // Create the destination image with same dimension as the source image 
   RasterImage destImage = new RasterImage(
