AutoPageSplitterCommand Class


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

  • 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.
