Using Gtk::Image and Gtk::Pixbuf, and a widget where you can move  
the images around, it is possible to draw … uh, images.  
A little bit like Gimp with fixed objects.

But, aside from making a Snapshot with something like ksnapshot,  
does anyone know of a way to get the current "assembled Images "  
from a widget (any widget at all)?

Specifically, I would like to make a “dumb” Image “drawing”  
application, and would like to be able to store the final  
image result somewhere. (Think of some flash  
applications that do that)

You can do with Gdk::Drawable and Gdk::Pixbuf.  
The following example snapshots your desktop.

require ‘gtk2’  
drawable = Gdk::Window.default\_root\_window  
pixbuf = Gdk::Pixbuf.from\_drawable(drawable.colormap, drawable, 0, 0,  
\*drawable.size)  
pixbuf.save(“x.png”, “png”)

Thanks,
