Copy

public void AddDecorationImage(
	Image image,
	int scale
)

Public Sub AddDecorationImage ( 
	image As Image,
	scale As Integer
)

public:
void AddDecorationImage(
	Image^ image, 
	int scale
)

member AddDecorationImage : 
        image : Image * 
        scale : int -> unit

Parameters

image: Type: System.DrawingImage
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
