Hello Paulo, << I guess that would be using Cairo so I can have a 2d canvas to draw in and maybe even preview before exporting to PDF. However, I can't find any documentation on Cairo with Haskell or any code examples related to what I want to do. >> With regard to export to pdf and other formats this might be useful: http://muitovar.com/gtk2hs/app1.html (There's a Spanish translation too.) However, this tutorial is a few years old now, and I don't know if it's still up to date for the later Gtk2Hs versions. Best Regards, Hans van Thiel
