dxBarCodeUPCALeftQuietZoneSize Constant

Specifies the left quiet zone size of the UPC-A symbology, in barcode modules.

Declaration

const dxBarCodeUPCALeftQuietZoneSize: Integer = 9;

Returns

Type
Integer

Remarks

The UPC-A barcode generator multiplies the dxBarCodeUPCALeftQuietZoneSize and dxBarCodeUPCARightQuietZoneSize global constant values by the barcode control’s Properties.ModuleWidth property value to determine the distances (in pixels) between the displayed barcode and the control’s left and right boundaries, respectively.

The first digit in the UPC-A encoded text can be invisible or truncated if the dxBarCodeUPCALeftQuietZoneSize global constant value is too low.
