'Declaration
 
Public Class CopyDataCommand 
   Inherits RasterCommand
   Implements IRasterCommand

'Usage
 
Dim instance As CopyDataCommand

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.

Public Sub CopyDataCommandExample()
      Dim codecs As RasterCodecs = New RasterCodecs()

      Dim srcFileName As String = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp")
      Dim destFileName As String = Path.Combine(LEAD_VARS.ImagesDir, "CopyDataCommand.bmp")

      ' Load the source image from disk
      Dim srcImage As RasterImage = codecs.Load(srcFileName)

      ' Create the destination image with same dimension as the source image
      Dim destImage As RasterImage = New RasterImage(RasterMemoryFlags.Conventional, srcImage.Width, srcImage.Height, srcImage.BitsPerPixel, srcImage.Order, srcImage.ViewPerspective, srcImage.GetPalette(), IntPtr.Zero, 0)

      ' Copy the image data from the source image to the destination image
      Dim command As CopyDataCommand = New CopyDataCommand()
      command.DestinationImage = destImage
      command.Run(srcImage)

      ' Save it to disk
