Gtk2::Image Loading a png from scalar

["William B Carlson" <carls107 msu edu>]

I have a library (GD::Graph, GD::Dashboard, etc) that can create an image 
and put it in scalar reference.  It can also make a physical file on the 
file system which I can load in with Gtk2::Image->new_from_file("file.png"). 

What I want to know is if there is a way to take the scalar
( my $image = $dash->png() ) that the library can produce and load that into 
the application without having to write the file to the file system and read 
it again. 

Thanks for your time,
