Hello Rado! Very nice editor! :-)
I was thinking of maybe being able to export to another format to be able to get drawings as well. A LaTeX package for drawing graphs that I like very much is tkz-graph, http://altermundus.com/pages/graph.html which is built on top of TikZ. I was playing around with the source of grapheditor.html and I uploaded what I got at http://fidelinux.googlepages.com/grapheditor.html I dont know how to get line breaks on the output. Here are some screenshots and samples of the output pdf file after processing it with LaTeX: http://fidelinux.googlepages.com/ss1.png http://fidelinux.googlepages.com/ss2.png http://fidelinux.googlepages.com/output1.pdf http://fidelinux.googlepages.com/output2.pdf http://fidelinux.googlepages.com/output3.pdf For more information on how to get the pdf files from outputted code you can see: http://graphtheoryinlatex.blogspot.com/2008/02/using-tikz2pdf.html I hope it is useful. I would also like to collaborate if you want. Thanks for your attention. Greetings, Fidel On Apr 30, 7:27 pm, Rado <rki...@gmail.com> wrote: > Thanks for the positive feedback.
