I have two PDF files, each has the same number of pages. I want a PDF file with the same number of pages, and each page is a superimposition of the pages of the same number in the two source files. As in, page 1 file 1 + page 1 file 2 = resulting page 1, etc.
With pdftk I can do it in a simple way:
pdftk file1.pdf multibackgroud file2.pdf output file3.pdf
However, I now need to do this on a Fedora machine, and Fedora does not have pdftk. And I can't build it because libgcj abd gcc-java are also absent.
As a last resort I can create an OpenSUSE VM, as OpenSUSE has pdftk. But perhaps there is a tool that can do the same job and is available on Fedora?
(I found CoherentPDF but it is licensed "not for commercial use", which is not something workable for me now).
