CloneCommand Class








Members 
Leadtools.ImageProcessing Namespace : CloneCommand Class
Creates a copy of a a RasterImage object.
Object Model
Syntax
public class CloneCommand : RasterCommand, IRasterCommand  
'Declaration
 

Public Class CloneCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
'Usage
 

Dim instance As CloneCommand
public sealed class CloneCommand : IRasterCommand  
@interface LTCloneCommand : LTRasterCommand
public class CloneCommand extends RasterCommand
function Leadtools.ImageProcessing.CloneCommand()
public ref class CloneCommand : public RasterCommand, IRasterCommand
Remarks

After the command is run, a copy of the current page of the source image will be in the CloneCommand.DestinationImage property. This property will hold a copy of the image, so the user is responsible for freeing this image after using it.

If a region is defined for the image, the region is also copied.

If the source image has more than one page, then you can use the CloneCommand.AllPages property to control whether to clone all the pages in the image or only the current page.

You can use the RasterImage.Clone method instead of this command to create a clone of an image. If you need to clone a multi-page RasterImage object, then use the RasterImage.CloneAll method. These methods will also clone any metadata (tags, comments and markers) located in the source image however, you lose the benefit of using a progress monitor.

Example

This example will load an image and then clone it before saving it back to disk. For an example on how to clone a multi-page image and show the overall progress monitor, refer to the CloneCommand.AllPages property.
