Subject Re: [SURVEY] PDFBox Uses Cases

I'm using PDFbox in my client's project to:

- set crop/media boxes to automatically crop whitespace and/or unwanted 
(the actual cut points are calculated with ghostscript bbox and text 
extraction from "suspect" unwanted areas)

- extract individual pages from foreign documents

- add overlays to existing documents (like a stamp "COPY" on an invoice 
PDF, highlighting a particular area on a page, or "underlay" a page with 
another document [eg. 'business paper'])

- extract text from foreign documents (or parts of such documents) for 

- "convert" images to PDF documents (in that case, one image per page)

What I would like to do is to "optimize" a document in a way that 
removes everything that is not related to the currently "visible" 
(possibly cropped) area of the document, including metadata. I once 
asked about metadata removal on the mailing list (see 

) but since that is still "only" a nice-to-have for my project, I have 
yet to look further into how to "write back the [modified] PDmetadata 
stream" (and then supply a patch ;-] ) .

Anyways, for me PDFbox has always been a very valuable tool. This survey 
is a perfect occasion to say THANK YOU to the busy community!

Best regards,
