Barcode.NominaSize specifies whether the image is to be drawn at the nominal size for the barcode
Default value 0 Some barcodes are specified by their designers to be reproduced at a nominal size (EAN and UPC codes are examples). This variable may be used to generate a barcode image that is at the nominal size rather than the size specified by the lpRectIn parameter in calls to BarCodem
Allowed values:
0 - Size specified in by ImageWidth and ImageHeight is used
1 - Nominal size is used and ImageWidth and ImageHeight are ignored
Note that for barcode types that do not have a nominal size this parameter is ignored.
