Example

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

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

 Dim srcFileName As String = LeadtoolsExamples.Common.ImagesPath.Path + "Image1.cmp"
 Dim flipExamplesImage1 As String = LeadtoolsExamples.Common.ImagesPath.Path + "Image1_horizontal.bmp"
 Dim flipExamplesImage2 As String = LeadtoolsExamples.Common.ImagesPath.Path + "Image1_horizontal.bmp"

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

 ' Flip the image horizontally (reverse)
 Dim cmd As FlipCommand = New FlipCommand()
 cmd.Horizontal = True
 cmd.Run(image)

 ' Save the image to disk
 codecs.Save(image, flipExamplesImage1, RasterImageFormat.Bmp, 24)

 ' Flip the image vertically
 cmd.Horizontal = False
 cmd.Run(image)

 ' Save the image to disk
 codecs.Save(image, flipExamplesImage2, RasterImageFormat.Bmp, 24)

 ' Clean up
 image.Dispose()
 RasterCodecs.Shutdown()
      End Sub
C# Copy Code
public void FlipCommandExample() 
{ 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = LeadtoolsExamples.Common.ImagesPath.Path + "Image1.cmp";

   // Flip the image horizontally (reverse) 
   FlipCommand cmd = new FlipCommand(); 
   cmd.Horizontal = true; 
   cmd.Run(image); 
 
   // Save the image to disk 
   codecs.Save( 
      image,

   // Flip the image vertically 
   cmd.Horizontal = false; 
   cmd.Run(image); 
 
   // Save the image to disk 
   codecs.Save( 
      image, 
      flipExamplesImage2, 
      RasterImageFormat.Bmp, 
      24); 
 
   // Clean up 
   image.Dispose(); 
   RasterCodecs.Shutdown(); 
}
