Making 1 page pdfs from a multipage pdf using itextsharp

I have a pdf that I want to make into several 1 page pdfs where each page in the original pdf is now its own pdf document. I am trying to do this using itextsharp, but am having some difficulty even getting started.

Am I going about this the wrong way? Anyone know how I would go about doing this?

Thanks a ton!

using (FileStream fs = new FileStream(argPdfFileName, FileMode.Create))
{
  Document doc = new Document(argReader.GetPageSize(argPdfPageNumber));
  PdfCopy copy = new PdfCopy(doc, fs);
  doc.Open();
  PdfImportedPage page = copy.GetImportedPage(argReader, argPdfPageNumber);
  copy.AddPage(page);
  doc.Close();
}

Chopped this out of some working code. argReader is a PdfReader instance pointing at the source document. argPdfPageNumber is the pagenumber in question. Basically you just create a new pdf. Import the source page into it and then add it to the document and save.

There are two different commandline tools which can do that, both for any of the major OS platforms available.

pdftk

Example commandline:

pdftk input.pdf burst output page_%04d-from-input.pdf

Ghostscript

Example commandline:

gs \
   -o page_%04d-from-input.pdf \
   -sDEVICE=pdfwrite \
    input.pdf

Caveats: It's only the most recent version of Ghostscript which supports this commandline syntax of %04d for page-wise different output files + names.

pdftk isn't able to do any PDF manipulation in the process and is very fast.

The new Ghostscript method somewhat slower, but has the advantage that it can apply a lot of its other PDF processing capabilities should you need them.

There is a different library, PDFSharp, that may be better suited for this. You can open a PDFDocument object, and go through each page individually, extracting it into is own, separate PDF document.
