Thanks, Gabor. This looks useful, as far as it goes. However, it doesn't deal directly with PS, so one would have to work to pixel resolution of screenshots as displayed by say 'gv'. In the case of an example such as the Fig 4 I mentioned in a previous post, this would involve taking several screenshots to "tile" over the entirety of the graph, since the pixel accuracy or a screenshot of the entire graph would be rather poor. This would introduce the neccessity of keeing track of points from screenshot to screenshot, and also each screenshot would have its own coordinate system so these would have to be reconciled before the final dataset could be compiled. But thanks -- this could well be worth a try in a different kind of context (e.g. I have some screenshots of old maps which I want to digitise ... ).
