You have some valid points there and I agree that PdfCopy should have a way of adding content. My idea here is to have two kinds of concatenaters/content adders:
- PdfCopy like to make an efficient use of memory. Read a document, change it, write it, get another. No form fields.
- PdfStamper like for flexibility. All the docs are in memory (except the streams) but everything can be done like adding and deleting fields, random access to pages, etc.

Subject: [iText-questions] PdfCopy and text additions
Hi
I've been using the iText package for a while and it works wonderfully well
(and fast)...but I've hit a problem
...basically I need to concatenate any number of PDF docs and stream them
back to the users with a bit of extra text on each page, say for example
'Page n of N' were each copied page has 'Page n of ' + template (Xobject)
added to it and when all required docs have been added the template is
written to with total pages. Sounds straight forward huh?
...PdfCopy does this well with a minimum memory usage - only one PDF is in
memory at a time as PdfCopy just writes each page out...great...but the
PdfImportedPage that is added to PdfCopy doesn't allow any additional
text...I don't want to add the PdfImportedPage objects as templates - via
addTemplate() as it defers the streaming out of PDF bytes until
PdfCopy.close()...
Also PdfContentByte.add(PdfContentByte) doesn't 'show' the added content -
why not?
What I'm asking may be impossible due to the nature of object references,
etc in the resultant PDF doc, but it doesn't sound unreasonable...basically
I'm looking for a combination of PdfCopy (merges existing PDFs) + PdfStamper
(allows an existing PDF to be written to)...
Thanks in advance
steve
