Breaking PDF into smaller PDFs

Using Smalltalk, I would like to break a PDF with 500 pages into 500 PDFs of one page each.
 
How can I do that?

Thanks,

A simple solution would be to install Ghostscript and use its command line
interface from Smalltalk. Ghostscript can process PDF files and write
one-file-per-page output, see
http://www.ghostscript.com/doc/9.06/Use.htm#One_page_per_file.

PDFsam might be an alternative, but it needs a Java Runtime Environment:

Alternative solution:
Load Christian Haider's PDF library from the public Store repository.
Then implement something like that:

| inputStream inputPDF pageNumber |
inputStream := 'ReleaseNotes7.7.pdf' asFilename readStream binary.
[
        inputPDF := PDF.File readFrom: inputStream.
        pageNumber := 1.
        inputPDF trailer Root pagesDo: [ : page |
                | targetFilename onePageDocument |
                onePageDocument := PDF.Document new.
                onePageDocument root addPage: page.
                targetFilename := (pageNumber printString, '.pdf') asFilename.
                onePageDocument saveAs: targetFilename.
                pageNumber := pageNumber + 1.
        ].
] ensure: [ inputStream close ].

Holger:

Thanks you very much for your help. The code helped perfectly.

My PDF has a bad reference and caused an exception. Christian Haider helped debug most promptly and graciously.

Thanks for all the help in the forum.
