Description: Instructs Toolkit to include quiet zones when generating the barcode.
Syntax: object.QuietZones = value
Arguments: Argument Value Type Description & Settings
object N/A Set to an instance of the object.
Value Variant_Bool True = include quiet zones.

False = Quiet zones are not included (Default).
Remarks: Quiet zones help scanners determine where a barcode begins and ends. In a linear barcode, the quiet zones are the empty spaces that precede the start character and follow the stop character. In a 2- dimensional barcode, the quiet zone is the area around the barcode. The quiet zone added is 10 times the value of NarrowBarWidth for all linear symbologies, 2 times PDFModuleWidth value for PDF417 barcodes, 2 times of DataMatrixModuleSize value for DataMatrix barcodes and 1 element width for MaxiCode barcodes.

NOTE: Setting QuietZones to true substantially increase the barcode length for linear symbologies. If you have set symbol margin properties you may safely set this property to False to better align the comment and human-readable text. You can refer to Symbologiesfor a description of each barcode symbology.
