Property: TrailingQuietZone

Specifies the horizontal width of the trailing quiet zone in modules.

Syntax:

property TrailingQuietZone: Integer;

Description:

Specifies the horizontal width of the trailing 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):

TrailingQuietZone property

This property is useful only when the ShowQuietZone property value is set to true or the barcode symbology is a TBarcode2D_Code16K symbol.

For the TBarcode2D_Code16K barcode component, the trailing quiet zone is represented always, even if the ShowQuietZone property value is set to false. See diagram (the SpaceColorproperty value is set to clSilver in order to accentuate the quiet zones):

TrailingQuietZone property (Code 16K)

For the TBarcode2D_CCA, TBarcode2D_CCB, and TBarcode2D_CCC barcode 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 trailing quiet zone begins from the last bar or space of entire EAN.UCC composite barcode symbol that includes the linear symbol. See diagram (the SpaceColor property value is set to clSilver in order to accentuate the quiet zones):

TrailingQuietZone property (CC-A, CC-B, CC-C)

Note, For the TBarcode2D_CCA and TBarcode2D_CCB barcode components, if the linear component is one of the TBarcode1D_UPCE, TBarcode1D_UPCE0, TBarcode1D_UPCE1, TBarcode1D_UPCA, TBarcode1D_ENA8, and TBarcode1D_EAN13, and its right quiet zone mark is represented (the TextAlignment property's value is set to taCustom, and for the TBarcode1D_ENA8 and TBarcode1D_EAN13 components, the ShowQuietZoneMark property is set to true too), the distance between the last bar of the 2D symbol and the right side of the right quiet zone mark of the linear symbol is included in the width of trailing quiet zone, and it's the minimum width of the trailing quiet zone. In other words, the trailing quiet zone always begins from the last bar of the 2D symbol. The minimum width will be used if the value of the TrailingQuietZone property is less than it or the value of the ShowQuietZone property is set to false, the trailing quiet zoens will be automatically extanded to cover the right quiet zone mark, regardless of whether the ShowQuietZone property is set to true or false. See diagram (the SpaceColor property value is set to clSilver in order to accentuate the quiet zones):

TrailingQuietZone property (CC-A, CC-B; TextAlignment = taCustom)

For all of the TBarcode2D_CCA, TBarcode2D_CCB, and TBarcode2D_CCC barcode components, if the linear component is the TBarcode1D_UPCE, TBarcode1D_UPCE0, TBarcode1D_UPCE1, TBarcode1D_UPCA, TBarcode1D_ENA8, TBarcode1D_EAN13, or TBarcode1D_EAN128, and its human readable text is represented and exceeds the end of entire barcode symbol (the trailing quiet zones is included if the ShowQuietZone property is set to true), the trailing quiet zoens will be automatically extanded to cover the human readable text, regardless of whether the ShowQuietZone property is set to true or false. See diagram (the SpaceColorproperty value is set to clSilver in order to accentuate the quiet zones):
