Creates a GdkPixbuf object based on a GD image object.
This method opens a range of possible interactions with PEAR packages: Any package that is able to produce GD images can be used to display its output directly in a GtkImage widget by loading the GD resource into a pixbuf.
The following examples uses the PEAR package Image_Graph to create a chart. Then it obtains internally used GD object and converts it to a GdkPixbuf, which itself is used as base for the GtkImage widget.
