I'm new here. As the layout editor of the electronic journal LMCS sitting on top of arxiv resp. CoRR, sometimes I encounter the problem that the TeX-implementation there does not produce the same output as I'm getting (with a clean installation of texlive2013). Sometimes even the number of pages changes :-(
Currently a paper contains two TikZ-diagrams that do not render correctly at CoRR. Unfortunately, I cannot use TikZ's externalization to produce separate pdf-files here that could be read in at CoRR, as the diagrams are built in a 2-step process with the tikzoverlay construct: all the building blocks are externalized, but the combined diagram fails :-(
What I'm looking for is a TeX-style that allows me to render the diagrams in question in a shrink-wrapped way, with all white space removed, i.e., just in the size of the bounding box. Alternatively, shrink-wrapping the resulting pdf-files for the individual diagrams would also help. Obviously, I would like to avoid extracting the diagrams as image files (which I know how to do). I have not found a way to extract them as pdf-files.
