12.39. QuietZones Property

Description

Returns or sets a value that determines whether to include quiet zones on the barcodes generated.

Syntax

object.QuietZones[= Boolean] 

Remarks

In linear barcodes, quiet zone is defined as a clear space that precedes the start character of a barcode symbol and follows the stop character. In two-dimensional barcodes quiet zones are clear area around the barcode. The space is required to help scanner determine where the barcode starts and stops.

The width of space added is 10 times the NarrowBarWidth value for all linear barcodes, 2 times PDFModuleWidth value for PDF417 barcodes, 2 times DataMatrixModuleSize value for DataMatrix barcodes and 1 element width for MaxiCode barcodes. Setting this property substantially increase the barcode length for linear symbologies.

You can also use symbol margins to create effective quiet zones. By default Barcode ActiveX set the symbol margins to 100 mils at 4 directions. When this is the case, you may safely set this property to FALSE to better align the comment and human readable text.
