I am using iText to populate a pdf form using data from our database. Sometimes, though, our forms may have an extra body of text at the end, like a disclaimer, depending on certain criteria specified in the data.
Is it possible to hide parts of a PDF document so they do not display / print? This would let our business people create the forms including the disclaimers, and we can programatically hide them. Or must we create different forms?
Put the elements you want to hide on a PDF optional content group (OCG). Also known as a layers. Layers can be shown or hidden, set to print or not, etc. You can control OCG status using iText.
