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: 7.6.3.1256-master

Syntax

void AddDecorationImage(
	string imageFileName,
	int scale
)

Sub AddDecorationImage ( 
	imageFileName As String,
	scale As Integer
)

void AddDecorationImage(
	String^ imageFileName, 
	int scale
)

abstract AddDecorationImage : 
        imageFileName : string * 
        scale : int -> unit

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 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
