simplest might be to just call out to `shellExec("import -window 
root filename.png");` and it will write the file.

Hmm, that's good idea as fast solution. Thank you Adam.

Hi Konstantin,

I've got a simple example in Vala language but it's very easy to 
rewrite it in D thank's to GtkD (and also thanks to Mike Wey for 
his work in GtkD!):

//  compile: valac --pkg gtk+-3.0 --pkg gdk-3.0  screenshot.vala

int main (string[] args) {
     Gtk.init (ref args);

     int  width, height;

     Gdk.Window win = Gdk.get_default_root_window();

     width = win.get_width();
     height = win.get_height();

     Gdk.Pixbuf screenshot = Gdk.pixbuf_get_from_window(win, 0, 0, 
width, height);

     screenshot.save("screenshot.png","png");
     return 0;
}

Ok, took the time to translate it to D and created a github repo 
to clone. You can download and try it from:

Hope It helps you.

class ApMainWindow : MainWindow

	this()
	{
		super("Screen Capture");
		setTitle("Screen Capture Example");

		VBox box = new VBox(false, 2);

		showAll();
	}
	
	void screenSave(Button button)
	{
		Window win = Window.getDefaultRootWindow();
		int width = win.getWidth;
		int height = win.getHeight;
		Pixbuf screenshot = getFromWindow(win, 0, 0, width, height);
		screenshot.savev("screenshot.png", "png", null, null);
	}
	
	void exitProg(Button button)
	{
		stdlib.exit(0);
	}
}
