Barcode Quickstart
The BarcodeWriter.CreateBarcode class can be used to create barcodes and QR codes from strings, numbers, or binary data and encode to an appropriate format. We can then use the SaveAsImage() method to export as an image, or other easy saving methods to save to a PDF, HTML, System.Drawing.Image, stream, or Bitmap object.
Likewise, we can read barcodes using the BarcodeReader class. The easiest method to use is the BarcodeReader.Read method, as shown above.
Do note all the various options set in BarcodeReaderOptions that allow you to customize your reading to be faster, more intensive, stop scanning after reaching one barcode to save time, specify specific types of barcode to search for, and utilize multithreading, among other customization options.
