I'm not entirely sure how fontconfig works or how Graphviz is loading the configuration file, though. Looking at the source code, I think it's being left up to whichever rendering plugin you're using. I had to change the comma after the default attribute list to a semicolon to get Graphviz to output an image, by the way.

I am now trying to figure out how to apply different fonts into the graph, so i tried to build a string as follow:

string g = "digraph Graphviz { charset=\"utf-8\", node[shape=ellipse, fontname=\"Courier\", fontsize=8], test1->test2}"

The rendering result in empty nodes, probably due to some font mapping problem. I noticed that there is a fonts.conf file in the msi install directory \etc\fonts , however the configuration only applies on the windows executable. Wonder if you got any idea to apply the config onto the web app package?

Cheers!

It worked fine when I tried it on my end. :)

Just make sure you have Graphviz 'bin' folder in your PATH variable on your IIS server if that's what your using this code for. You may have to restart the IIS server.

Thanks for pointing out the errors. I've fixed the const typo and will re-upload a new image showing the missing graph node soon.

As for your font problem, have you tried specifying a default font attribute for your graph? It could be that Graphviz is trying to render with a font that doesn't exist on your installation (I'm just throwing ideas out there, as I'm not a Graphviz expert by any means). Other than that, I don't know what the problem could be. If I get a chance, I'll spin up an XP VM and try it out.

Do you get the same results using the dot program that comes with Graphviz?

Thanks for this page. It was very helpful.
A couple of minor typo's in the page I think:
< public const string LIB_GVA = "gva.dll"; > should be < public const string LIB_GVC = "gvc.dll"; >
The string dot contains a node "graph" which is not rendered, I guess because it is a reserved word. If you allchange it to "zgraph" it is rendered.
When I display this in a C# winform on XP, the graph is rendered but all the characters in the node labels come out as blocks. Any ideas? I wonder if this is to do with unicode?

Sorry I let others do the dirty work.

And therefore thanks again!

Apologies for not updating it for 5.0 sooner. I haven't used DocBook in a while, so I wasn't aware that I new version had been released.

That's... fast!

Thanks a lot!
