HOW TO: Split Scans on Blank Page or Patch Codes for Twain

Attached is a sample C# project that uses the Leadtools.Twain NuGet from LEADTOOLS. This project uses the TwainSession to acquire pages from a TWAIN compliant device using the Acquire method and AcquirePage callback (which intercepts each separate page scanned and handles the image). Once it acquires a page, it uses the BlankPageDetectorCommand to determine if the page is blank, then uses the BarcodeReader’s ReadBarcodes method (searching only for the PatchCode BarcodeSymbology). If the page isn’t a separator, it uses the RasterCodecs to append the pages to a TIFF using the Append CodecsSavePageMode.
