'Declaration

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

'Usage

Dim instance As AutoPageSplitterCommand

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.
