Add options -format,-file for PNG/SVG file output #39

Closed Russtopia closed 5 years ago

Russtopia commented 5 years ago

Addition of -output, -svg, -png options to run go-callvis in a non-server mode to just output image files. Useful for scripting eg., makefile targets to generate graphvis for modules non-interactively.

@Russtopia It would be really great if you could also update few examples that show command usage with parameters, because they don't currently show something that would work with latest version.

Sure, I should have done that with the original patch.

Newest PR updates examples, but I had to guess at the last example -- I'm unfamiliar with 'exo-open' but from the context it appears to take the SVG output and convert to JPG?
