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

Attached is a sample C# project that uses the Leadtools.Wia NuGet from LEADTOOLS. This project uses the WiaSession to acquire pages from a WIA version 1.0 compliant device (you can configure the project to use version 2.0) using the Acquire method and AcquireEvent callback (which intercepts each separate page scanned and handles the image). In order to use the callback to intercept the pages, the project first configures the properties of the scanner to transfer a RawRgb image over Memory rather than a file (which is default). 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.
