Clone() Method

Summary

Creates an exact copy of the current page of this RasterImage.

Syntax

C#
VB
Java
Objective-C
WinRT C#
C++
public RasterImage Clone() 
Public Overloads Function Clone() As Leadtools.RasterImage 
public Leadtools.RasterImage Clone() 
- (nullable LTRasterImage *)clone:(NSError **)error 
public RasterImage clone() 
 function Leadtools.RasterImage.Clone()() 
public: 
Leadtools.RasterImage^ Clone();

Return Value

The RasterImage this method creates.

Remarks

You can also use the /#ctor constructor to create an exact copy of an existing RasterImage.

To create a copy of an object while maintaining a progress status, refer to the CloneCommand.

This method copies only the current active page and no metadata information is copied. To create an exact copy of a RasterImage object use the CloneAll method.

To clone an image with support for a progress event, refer to CloneCommand.

Example

This example loads a multi-page image and clones it in 3 different ways.
