Image to add to barcode.
Scale of the image square relatively to the barcode square, in percents. Recommended is 15 percents with the highest error correction level. Set -1 to disable the scaling.
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
