int  nominal_size

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 lpRectIn is used

1 - Nominal size is used and lpRectIn is ignored

Note that for barcode types that do not have a nominal size this parameter is ignored.
