Declaration

This element is declared as an instance of BarcodeConfig class. Reference Aspose.OMR.Generation.Config.Elements and Aspose.OMR.Generation.Config.Enums namespaces to use ContentConfig types without specifying the fully qualified namespace:

using Aspose.OMR.Generation.Config.Elements;
using Aspose.OMR.Generation.Config.Enums;

A string encoded as a barcode is specified in the Value property.

new BarcodeConfig() {
	Value = "Encoded string"
}

Required properties

Name	Type	Description
Value	string	A string encoded as a barcode.

Optional properties

Name	Type	Default value	Description
Name	string	n/a	Used as an element’s identifier in recognition results and as a reminder of the element’s purpose in template source; for example, “Web site”. This text is not displayed on the form.
BarcodeType	Type of the barcode, a value from Aspose.OMR.Generation.Config.Enums.BarcodeType enumerator.	BarcodeType.QR	Type of the barcode.
BarcodeQRVersion	QR code version, a value from Aspose.OMR.Generation.Config.Enums.QRVersion enumerator.	QRVersion.Auto	QR Code version. Only applicable when BarcodeType is QR.
DrawCodetext	bool	false	Add a string from the Value property below the barcode image.
Align	AlignmentEnum	AlignmentEnum.Center	Horizontal alignment of the barcode image.
Height	int	Automatic	Barcode height, in pixels. The width is adjusted automatically.
X	int	n/a	Set the absolute position of the barcode relative to the left edge of the page. Overrides the value of Align property.
Y	int	n/a	Set the absolute position of the barcode relative to the top edge of the page.
RotationAngle	int	n/a	Rotate the element by the specified angle (in degrees). Negative angle rotates the element counter-clockwise, positive angle rotates the element clockwise.
