true to use XModule when writing barcodes of this type. Otherwise, false. The default value is false.
When the value of UseXModule is set to false, then the smallest module size is calculated from the size of the barcode data (BarcodeData.Bounds).
When the value of UseXModule is set to true, then the smallest module size is set in XModule and the barcode data size may be used as a "clipping" boundary.
For more information, refer to Writing Barcodes - Bounds and XModule.
