Implements
IBarcodeAddDecorationImage(String, Int32)Note, the embedded image damages the barcode, but the QR Code's error correction algorithm makes it possible to decode the damaged barcode if the damage doesn't exceed 7-30% of barcode square (depending on the error correction level). See
Options and
QRErrorCorrectionLevel. It's recommended to generate the QR Code with highest error correction level and check the barcode is still decodable after image applying. To read the barcode you can use ByteScout Barcode Reader SDK: https://bytescout.com/products/developer/barcodereadersdk/bytescoutbarcodereadersdk.html
