property TopQuietZone: Integer;
Specifies the vertical height of the top quiet zone in modules. The quiet zone is represented using the color specified by the SpaceColor property if the Inversed property is set to false. Otherwise, it's represented using the color specified by the BarColor property. See diagram (the SpaceColor property value is set to clSilver in order to accentuate the quiet zones):
This property is useful only when the ShowQuietZone property value is set to true.
For the TBarcode2D_CCA, TBarcode2D_CCB, and TBarcode2D_CCC components, if the Linear property is set, the 2D symbol and the linear symbol are assembled to generate an EAN.UCC composite barcode symbol, the top quiet zone is close to the top boundaries of entire EAN.UCC composite barcode symbol, namely, the top boundaries of the 2D symbol. See diagram (the SpaceColor property value is set to clSilver in order to accentuate the quiet zones):
