Object Model
Syntax
public class FlipCommand : RasterCommand, IRasterCommand  
'Declaration
 

Public Class FlipCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
'Usage
 

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

This command can flip an image from top to bottom (vertically) or from left to right (horizontally).

Example

This example will load an image and then flip it before saving it back to disk.
