I have updated the Barcode Multipass Demo project to version 20 of our SDK using Visual Studio 2017. This project was originally part of the 25 projects in 25 days promotion. This demo attempts to detect and read all barcodes of a document, and, if unsuccessful, it resizes the image and adjusts the image's DPI for a second pass. This method is often successful for low resolution barcodes that would not be able to be detected otherwise.

The full source code for this project can be downloaded at the following link:
