Steve: Thanks for these. I tried most of them out on a sample program and many of them worked fine. But I couldn’t figure out how to get them to bold / italic / underline etc., which is what I was particularly concerned about. .
The reason for the OP was that I’d read this in the Graphviz documentation:
Note that various font attributes, such as weight and slant, can be built into the font name. Unfortunately, the syntax varies depending on which font system is dominant. Thus, using
fontname="times bold italic" will produce a bold, slanted Times font using Pango, the usual main font library. Alternatively,
fontname="times:italic" will produce a slanted Times font from fontconfig, while
fontname="times-bold" will resolve to a bold Times using Quartz. You will need to ascertain which package is used by your Graphviz system and refer to the relevant documentation.
Since I’m using WebGraphviz.com, presumably this information is only available to whoever put that program together (or, if that person documented it, some other person who knows where the documentation is). Here’s hoping those people track the Forum queries occasionally.
