Leadtools.ImageProcessing Namespace : CopyDataCommand Class



Copies image data from one image to another.

Object Model


Syntax

Visual Basic (Declaration)  
Public Class CopyDataCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code
Dim instance As CopyDataCommand
C#  
public class CopyDataCommand : RasterCommand, IRasterCommand 
C++/CLI  
public ref class CopyDataCommand : public RasterCommand, IRasterCommand 

Example

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

Visual Basic Copy Code
Public Sub CopyDataCommandExample()
 RasterCodecs.Startup()
 Dim codecs As RasterCodecs = New RasterCodecs()

 Dim srcFileName As String = LeadtoolsExamples.Common.ImagesPath.Path + "Image1.cmp"
 Dim destFileName As String = LeadtoolsExamples.Common.ImagesPath.Path + "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
 codecs.Save(destImage, destFileName, RasterImageFormat.Bmp, 24)

 ' Clean Up
 srcImage.Dispose()
 destImage.Dispose()
 RasterCodecs.Shutdown()
      End Sub
C# Copy Code
public void CopyDataCommandExample() 
{ 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = LeadtoolsExamples.Common.ImagesPath.Path + "Image1.cmp"; 
   string destFileName = LeadtoolsExamples.Common.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( 
      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 
   CopyDataCommand command = new CopyDataCommand(); 
   command.DestinationImage = destImage; 
   command.Run(srcImage); 
 
   // Save it to disk 
   codecs.Save(destImage, destFileName, RasterImageFormat.Bmp, 24); 
 
   // Clean Up 
   srcImage.Dispose(); 
   destImage.Dispose(); 
   RasterCodecs.Shutdown(); 
}

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