Size of GtkImage?

Hello,

I'am trying to dynamicly resize a GdkPixbuf, if the GtkImage that shows
the Pixbuf is reasized.

That means, if the GtkImage is getting bigger, the GdkPixbuf should be
replaced by a scaled GdkPixuf.

I allready looked at the API at gtk.org, but couldn't find a function,
that returns the actual size of the GtkImage in Pixels, to scale the
Pixbuf.

Is there a way to retrieve the size of the GtkImage?

Mfg

Matthias
