Add data to an exisiting pdf
by javaiTextUser

Rate this Message:
I just started using iText and had a question. I need to take an existing pdf and add some more data to it. If there is space to add data to the last page of the existing pdf, the new data needs to be appended there. If not, then I need to add a new page to the pdf and put the data in there. Is there a way to do this using iText.
Thanks.

Is there a way to do this using iText. Thanks. Add data to an existing PDF: that's easy. It's explained on different places on the net and in the book. Find out the available white space on a page: that's difficult (I'd say impossible) with iText. Summarized: it's possible, but only if you know the coordinates of the white space (and that may be impossible). br, Bruno ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

This is what I need to do -
1. Create a pdf file from given data (Easy using iText) 2. At a later point, reopen this pdf and add some more data to it I am not quite sure how to do this. Is there a way to get all the data in the pdf into a byte array, add more data to the byte array and recreate a pdf?

You really, really need to get a copy of the book, if you don't wish to be caught for fraud with the name you've assumed. As a *real* Java-iText user, you should have a copy of the book. You can get it in minutes from www.manning.com. Once you have the book, see the HelloWorldStamper example in Chapter 2. This shows you just one of the ways that you can do what you've decribed. Best regards, Bill Segraves P.S. I see you're with GE. Surely, GE would benefit from hiring Bruno to do a seminar on iText. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

When you reopen the document, ask the document for that invisible field and its coordinates. Then use PdfStamper to add new content and new pages. I'd also follow Bill's advice ;-) -- This answer is provided by 1T3XT BVBA ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

An alternative (and, IMO, a better) solution to putting the data in a
hidden annotation is to put it in an embedded file/attachment in a standard format (CSV, XML, etc.). That makes it cleaner, more standard and easier to access for both you and others. (and should also be less code to write ;) Leonard On May 17, 2008, at 6:02 AM, 1T3XT info wrote: > javaiTextUser wrote: >> This is what I need to do - >> >> 1.
