1. Use Gdk.Pixbuf.savev instead of save if you want to change container options upon saving file.

   Gdk.Pixbuf pixbuf = new Gdk.Pixbuf.new_from_whatever();
   pixbuf.savev("foo.jpg", "jpeg", 
                   new string[1]{"quality"}, 
                   new string[1]{"80"}); //this sets image quality to 80

   Refer gdk-pixbuf/io-<formatname>.c function real_save_<formatname> for options' list.
