Fortunately, a question relating to this error exists on StackOverflow: This gave me a DLL import error when I tried to use it. While Googling 'pycairo install windows' does give the above link, it is presented below some rather unhelpful pages, and it's also not particularly obvious that igraph documentation will be applicable.Įventually I got as far as installing P圜airo (from the GNOME link in the question), without Cairo itself. Hopefully people in a similar situation in future will find this post :) I asked the question above, so that I could answer it myself.

This will work on all platforms and with older Gdk versions. A second choice (recommended for older versions of Gtk) is to use a function provided in the Mono.Cairo samples.You can create a cairo context for a given drawable:Ĭairo.Context context = (drawable) Beginning in Gtk# 2.8, the Gdk.CairoHelper class provides cairo access to Gdk drawables.To use Cairo in Gdk/Gtk applications, a Context with a Gdk.Drawable target surface is needed. Surface can be window on the screen, an off-screen buffer or a static file on the disk. A Context is always attached to a Surface.
