You are probably using the example literally. You don't have to create all the files in memory. You could create every PDF as a file, then afterwards concatenate them, saving a lot of memory. Moreover section 16.1.5 of the book will give you some tips on how to save CPU (read page 512). However, with this approach, you will still end up with huge PDF files. > The second (http://itext.ugent.be/articles/eid-pdf/test/BatchFormFill.java) > possible solution is to extract the fields coordinates from the > PDF and then to simply add the form as a template to the > getDirectContentUnder() and in the second step to draw the data values > to the coordinates of the form fields.

Retrieving the font defined by the designer is not impossible, but may be difficult, depending on what to expect (Chinese? Arabic?
