PdfUnidimensionalBarcode drawn incorrectly using default values Declined - Not Valid

When the default bar height (80 pt) is used, the barcode is drawn with a bar height of 65.752 pt. After the barcode is drawn, the bar height is now 65.752 pt and the barcode.Size.Height is updated to 80 pt. I would expect the bar height of the drawn barcode to be 80 pt and not be updated by calling the Draw function.
