Let me begin with a confession: when someone says ``command line'' I nearly pee because I get so scared. I know that means I'm asking my question to the wrong community, and yes, I'm seeing someone about my problems. I don't want to talk about it anymore.
This thread asks almost exactly the same question I am interested in. I have two small additions to that post: is it possible to do the exact same thing for a xypic image (I would assume this is the case), and how do I do the part that's all ``code-ish''?
For those who don't want to go read the other thread, here's the simple version: I have three xypic drawings that I want to make .png or .jpg (or whatever) files from. How do I do that?
In case it matters: I use a mac with OSX10.8.4 installed, and when I try really really hard I've managed to find and open a terminal window in the past. I then usually get scared and run away.
