load image into cairo on mono

I looked around for a way to load a png into Cairo using Mono (C#) binding of the library but the closest I got was that in C-binding of the library something like cairo_image_surface_create_from_png() was used. However, in C#-binding of the library I didn't see any useful static members under Cairo.ImageSurface.*. Somewhere an old article mentioned that the binding is incomplete, is this the case? Currently I'm using Gdk.Image.Pixbuf to load in-memory (embedded) images but saw that Gtk+ have moved on to Cairo and that Windows.Forms in Mono are using Cairo, I thought the Cairo's C#-binding would at least be completed enough to include image loading. I'm probably missing something?

I've done this quite recently. You need to load your image into a Cairo Surface:-

var icon = new ImageSurface( pngfile );

Then you can use the ImageSurface.Show method to render it:

icon.Show( ctx, x, y );

See more useful things at the Mono.Cairo Cookbook page.
