public class CopyDataCommand : RasterCommand, IRasterCommand

'Declaration
 
Public Class CopyDataCommand 
   Inherits RasterCommand
   Implements IRasterCommand

'Usage
 
Dim instance As CopyDataCommand

public sealed class CopyDataCommand : IRasterCommand

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 RasterCommand.Run method to the image passed in the DestinationImage property.
