Syntax

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

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); 
          
}
