Re: Creating Gdk::Pixbuf from string data

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

Unfortunately, it won't work. When I tested to_string() on a 
Gdk::Pixbuf, it returned an empty string.

I agree that the documentation is unclear. I checked the source code of 
the underlying C classes, GdkPixbuf and GIcon.
GdkPixbuf implements the GIcon interface, but it only implements part of 
the interface. It does not implement the virtual functions to_tokens() 
and from_tokens(), and therefore a GdkPixbuf can't be serialized to a 
string. Nor can it be created from a string.
