public class CopyDataCommand : RasterCommand, IRasterCommand

'Declaration

Public Class CopyDataCommand 
   Inherits RasterCommand
   Implements IRasterCommand

'Usage

Dim instance As CopyDataCommand

public sealed class CopyDataCommand : IRasterCommand

@interface LTCopyDataCommand : LTRasterCommand

public class CopyDataCommand extends RasterCommand

function Leadtools.ImageProcessing.CopyDataCommand()

public ref class CopyDataCommand : public RasterCommand, IRasterCommand

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.

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