TestBoxField.AddBarcode

Question:

I'm using the trial version of Aspose PDF. I found the method "AddBarcode". I'm trying to use that to enter a barcode into an existing form field. However, when I use it to enter a value (let's say mytextfield.AddBarcode("123456")) it enters that value 123456 into the textbox and sets it to read only, but it does NOT convert the text to a barcode.

- Do I need to also have the barcode library installed to use this?
- Could this be a limitation of the trial software?

Thanks, Jeremy
