QRCodeAddDecorationImage Method (String, Int32)

Adds decorative image to draw in the center of the QR Code.

Namespace:Bytescout.BarCode
Assembly: Bytescout.BarCode.QRCode (in Bytescout.BarCode.QRCode.dll) Version: 1.7.1.1185-master
Syntax
public void AddDecorationImage(
	string imageFileName,
	int scale
)

Parameters

imageFileName
Type: SystemString
Image to add to barcode.
scale
Type: SystemInt32
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.
Remarks
Note, the embedded image damages the barcode, but the QR Code's error correction alorithm 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 QROption_ErrorCorrectionLevel. 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
