The Barcode Reader SDK can recognize barcodes with 0, 90, 180 and 270 degrees clockwise rotation. You can instruct the Barcode Reader to detect barcodes at one only orientation or by combining some of them (like 0 + 90 degrees). If you are sure that all barcodes will appear oriented in a particular way, for example, all the barcodes are rotated 180 degrees; then you should take advantage of that by setting up 180 degrees barcode rotation to speed up the recognition process.



To set up the barcode rotation, you use the BarcodeRotation property of the BarcodeReaderHints object which you must then attach to the BarcodeReader object. Please open the accompanying source code of the Barcode Reader sample app using Visual Studio 2005, 2008 or 2010 to learn how the BarcodeRotation can be set up using your preferred .NET language.
