Reading barcode from image stream in C# application is an easy work. C# developers can implement fast UPC-A bar code recognition from image string with the help of following APIs. By defining a file path, image source can be quickly loaded and UPC-A barcodes on it will be scanned and decoded within seconds.
The first API is for all barcodes reading and the second one is used to decode UPC-A from loaded image only. And here, we give you a C# sample code for implementing UPC-A barcode scanning. APIs for reading UPC-A from stream or bitmap of image are also illustrated.
