Remarks

The QRBarcodeWriteOptions class is used to control the options when writing QR barcodes using LEADTOOLS. Set the options in two ways:

The BarcodeWriter class contains default options for each barcode symbology (or group of common symbologies). These options can be retrieved using the BarcodeWriter.GetDefaultOptions method, passing BarcodeSymbology.QR. Then change the members of the returned QRBarcodeWriteOptions by casting it from BarcodeWriteOptions to QRBarcodeWriteOptions.

You can also create an instance of the QRBarcodeWriteOptions class and use it directly in the BarcodeWriter.WriteBarcode method which accepts the options as an input parameter.

The base BarcodeWriteOptions contains the following members and features:

Member Description
BarcodeWriteOptions.ForeColor

Controls the barcode foreground color (color of the bars or symbols) to use when writing a barcode to an image.

BarcodeWriteOptions.BackColor

Controls the barcode background color (color of the spaces) to use when writing a barcode to an image.

BarcodeWriteOptions.Load and BarcodeWriteOptions.Save

Can be used to save or load the options to/from an XML file or stream.

BarcodeWriteOptions.GetSupportedSymbologies
