Re: [Vala] problems with Gdk.Pixbuf.from_stream_at_scale_async

[yannick inizan <inizan yannick gmail com>]

gdk-pixbuf-2.0 vapi hasn't been updated : all methods which end with _async
are async methods. please use this "old" creation method :

Gdk.Pixbuf pixbuf = null;
Gdk.Pixbuf.new_from_stream_at_scale_async.begin (stream, 100, 100, true,
null, (obj, res) => {
pixbuf = Gdk.Pixbuf.new_from_stream_at_scale_async.end (res);
});
