I'am not very happy to implement where distros packaging fail. But .. if there is really a need for, I will do so. Lets see how this series goes upstream and feel free to remind on my words if I completely suppressed the idea after upstream. :) -- Markus --

There, it uses graphviz version 2.38, with is the same version as used on Fedora 25. That is with just graphviz: mchehab@OpenSuse:~/docs> dot -Thelp Format: "help" not recognized.

Ok, I discovered that, on Fedora, support for pdf, png and some other formats are packaged on a separate package: graphviz-gd.x86_64 With it installed, it now shows "pdf": $ dot -Thelp Format: "help" not recognized.

I'll try to investigate it further, as I found myself useful to produce PDF directly from GraphViz. Anyway, I guess we should modify kfigure.py to check if PDF is available, falling back to SVG, using ImageMagick to convert from SVG to PDF. Thanks, Mauro

See http://www.graphviz.org/News.php .. """New Release 2.32 (1 August 2013) ... In addition, if the poppler library is available, Graphviz can now use PDF files as images.""" I suppose that 2.32 is in your distro .. it's from 2013 It seems, that the graphiz homepage is not up to date. I found the repo at github. There is a issue about PDF https://github.com/ellson/graphviz/issues/1180 So I guess graphviz is compiled without HAVE_PANGOCAIRO in your distros? -- Markus --
