Visual BasicCopy 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
