AutoPageSplitterCommand Class

Summary

The AutoPageSplitterCommand automatically splits an image of two document pages that are side-by-side.

Syntax

C++

public class AutoPageSplitterCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Public Class AutoPageSplitterCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public ref class AutoPageSplitterCommand : public Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

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.
