plot_cfg(): Plotted CFG is not readable about angr-utils HOT 2 CLOSED

Many thanks for the input @axt
It is working fine using format as SVG. So basically no changes were done with respect to dot command, just added format='svg' within plot_cfg().

from angr-utils.

I think it's a problem of the dot command, when saving large graphs into png.

I would propose, that instead of using the png format as output, add format='raw' parameter to plot_cfg, to save the graph in raw format. (Or you can try format='dot', which is similar to raw, but calculates the graph layout before dumping the data, slower at creation, easier when using the graph).

You can view this raw graph for example with the xdot command in linux (I prefer this way over png), but I guess there are other tools to view dot files on any OS.

The framework uses the dot command from the graphviz, to turn a raw graph into png:

dot -Tpng graph.raw > graph.png

If you figure out what command options, or graph attributes need to be added, to make the render not blurry, i can add support for it in the framework.
