Undo Pdfnup Operation

Question

I have a Pdf file which contains several slides per page, including text (not only images). This pdf was probably created using pdfnup. Can I revert the pdfnup operation so that each slide is shown on one page?

Answer 1

As far as I know, there is no simple to be used 'undo' operation.

However, the following answers show you the approach principle, how you can achieve the undo-equivalent operation using Ghostscript:

• Convert PDF 2 sides per page to 1 side per page (Superuser)
• How can I split a PDF's pages down the middle? (Superuser)
• Cropping a PDF using Ghostscript 9.01 (Stackoverflow)
• PDF - Remove White Margins (Stackoverflow)

_{(Should these not help you to find the final solution, ask again. But then to come up with a fully working commandline, I'd need the complete output of the following command first: pdfinfo -f 1 -l 100 -box your.pdf.)}
