Barcode Xpress detects all barcodes in an image and gives you complete details about them.
If you know where on the image the barcodes reside, setting the ReaderAreaHeight, ReaderAreaWidth, ReaderAreaX and ReaderAreaY values to define a smaller rectangular area on your image will speed up processing. By default these values are set to 0 which tells Barcode Xpress to search the entire image automatically.
Barcodes supported for recognition are listed in the Barcode Xpress Overview. The edition you have enabled will determine exact barcodes.
Use the following methods and properties to recognize the barcode.
See the Barcode Xpress Overview topic for code examples on recognizing barcodes.
