I have multiple small fragments as PDF file, depending on user input these fragments has to be combined to one page.
pdfjam and/or pdfnup do this, and works. However, the default layout is according to the pdfpages doc.
The inserted logical pages are being centered on the sheet of paper by default.
I would need to combine individual PDFs to one page starting on top with no space/margin between them.
My current command looks like:
pdfnup 1.pdf 1a.pdf 2.pdf 2a.pdf --nup 1x4 --no-landscape --outfile test.pdf
Other solutions besides pdfjam would be OK.
