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	This class overrides the base class method to return an array containing the following symbologies: BarcodeSymbology.QR

In addition to these features and members, the QRBarcodeWriteOptions contains these QR barcodes specific features:

Member	Description
HorizontalAlignment	Horizontal alignment for the barcode inside the destination bounds.
VerticalAlignment	Vertical alignment for the barcode inside the destination bounds.
GroupNumber	The group number to use when writing QR barcode.
GroupTotal	The group total to use when writing QR barcode.
XModule	The size of the smallest module when writing a QR barcode.
ECCLevel	The ECC (Error Correction) level to use when writing QR barcodes.

For an example, refer to QRBarcodeData.
