IBarcodeAddDecorationImage Method (Image, Int32)ByteScout Barcode SDK
Add decorative image to draw in the center of the barcode. (!) Supported with QR Code only.

Namespace:  Bytescout.BarCode
Assembly:  Bytescout.BarCode (in Bytescout.BarCode.dll) Version: 7.3.1.1185-master
Syntax

void AddDecorationImage(
	Image image,
	int scale
)

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 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
