Unfortunately, the svg rendering engine in Firefox and Chrome doesn't support the magnification trick. I don't know if it ever will. There was a lot to like about Adobe's SVG Viewer plugin but Adobe killed the product 4 years ago. > >> and either go through >> machinations to print it in tiles > I like that idea, and will check it out, but now it will likely be later > next week as we're headed to NYS over the weekend, Thursday I'm told. Well, I gave alternatives because I think the required "machinations" are clumsy. I forget the search term I used to find instructions out there in Internet land, some mix of poster and svg I suppose. > <...> >> you could modify the Rockhopper Python script >> so that in addition to creating the SVG file Graphviz would also create >> and save a PDF file for further use. > That would be useful only if the PS engine can be convinced to output a > 2400 dpi image before its compressed from the 2+ gigabytes of raw data that > would generate. 72 dpi won't cut it. > You're thinking of an uncompressed bitmap. The diagram is line art that is mostly white space. Compression techniques deal with that. As well, cranking the resolution up to 2400 dpi shouldn't be necessary. For the example configuration file configs/sim/axis/axis.ini, the size of the halgraph.svg file saved from the browser is of order 50 KB. Open it in Inkscape and "save as" a PDF file with default settings (I forget exactly; something less than 100 dpi IIRC). The PDF file size is less than 25 KB. Open the PDF file in the Gnome Document Viewer. Zoom to 400 percent and wait a while for the renderer to catch up. Result looks great. Unfortunately, the Document Viewer doesn't know how to print out tiled pages...let me rephrase that...I don't know how to make the Document Viewer print out tiled pages and as far as I know my printer driver doesn't support that function either. Hope your trip goes well. To quote the old Hill Street Blues show, "let's be careful out there."
