Summary
The AutoPageSplitterCommand automatically splits an image of two document pages that are side-by-side.
Syntax
C#
Objective-C
C++/CLI
Python
public class AutoPageSplitterCommand : RasterCommand 
@interface LTAutoPageSplitterCommand : LTRasterCommand 
public ref class AutoPageSplitterCommand : public RasterCommand   
class AutoPageSplitterCommand(RasterCommand): 
Remarks
  • The input image can only contain two pages in horizontal order.
  • Generates two new RasterImage images with same original document dimensions.
  • After running the command, the SplittingCoordinate property provides the X-axis location of the split.
  • After running the command, the FirstImage property provides the page on the left side.
  • After running the command, the SecondImage property provides the page on the right side.
  • This command only processes the entire image; regions are ignored.
  • This function supports 24 and 36-bit color images and 8-bit grayscale images.
  • The command will fill the FirstImage and SecondImage properties with 1-bit RasterImage images.
Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Core; 
 
public void AutoPageSplitterCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage DocImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ScannedBook.jpg")); 
 
   //Binarize image 
   ColorResolutionCommand command = new ColorResolutionCommand(); 
   command.BitsPerPixel = 1; 
   command.Run(DocImage); 
 
   // Clean up border 
   BorderRemoveCommand BorderCommand = new BorderRemoveCommand(); 
   BorderCommand.Flags = BorderRemoveCommandFlags.AutoRemove; 
   BorderCommand.Run(DocImage); 
 
   // Split pages 
   AutoPageSplitterCommand SplitCommand = new AutoPageSplitterCommand(); 
   SplitCommand.Run(DocImage); 
 
   // Get left Page 
   RasterImage LeftPage = SplitCommand.FirstImage; 
 
   //Expand the content of the left page  
   ExpandContentCommand ExpandComment = new ExpandContentCommand(); 
   ExpandComment.Run(LeftPage); 
 
   // Save the resulting image 
   codecs.Save(LeftPage, Path.Combine(LEAD_VARS.ImagesDir, "LeftPage.bmp"), RasterImageFormat.Bmp, 24); 
 
   // Save the right page 
   codecs.Save(SplitCommand.SecondImage, Path.Combine(LEAD_VARS.ImagesDir, $"RightPageAt{SplitCommand.SplittingCoordinate}.bmp"), RasterImageFormat.Bmp, 24);
