[Gtk-sharp-list] How can I save a cairo imagesurface as a pixbuf

[Andy Selvig]

Alan-

Try creating a Gtk.DrawingArea, then use Gdk.CairoHelper to create a Cairo
context to draw to. Then you can use Gdk.Pixbuf.FromDrawable to create the
pixbuf. Something like:

Gtk.DrawingArea area = new Gtk.DrawingArea();
using (Context cr = Gdk.CairoHelper.Create(area.GdkWindow))
{

}
