I think it makes perfect sense for GeglGraph to be moved into or possibly subclassed from GeglNode. The concepts are similar enough to warrant such a change. In response to Samee's post, I don't care much for a stabilized API at this point. The C# bindings are automatically generated by GAPI. The bindings thunk down into native code so it's not like I'm re-writing GEGL in C#. However if a new library is released then the .so version is bumped and it doesn't really affect my bindings at all. In the worst case I can always statically link for the short term. george On Sun, 2006-29-10 at 02:37 +0200, Øyvind Kolås wrote: > On 10/28/06, George Talusan <george@xxxxxxxxxxx> wrote: > > Hello, > > > > I too am interested in a gegl-sharp library in particular for F-Spot. > > > > I've used GAPI to create a set of managed bindings for GEGL.
