Taking a screenshot with C\GTK

Question

I'm trying to take a screenshot of the entire screen with C and GTK. I don't want to make a call to an external application for speed reasons. I've found Python code for this (Take a screenshot via a python script. [Linux]); I just need to figure out how to do that in C.

Answer 1

After looking at the GNOME-Screenshot code and a Python example, I came up with this:

GdkPixbuf * get_screenshot(){
    GdkPixbuf *screenshot;
    GdkWindow *root_window;
    gint x_orig, y_orig;
    gint width, height;
    root_window = gdk_get_default_root_window ();
    gdk_drawable_get_size (root_window, &width, &height);      
    gdk_window_get_origin (root_window, &x_orig, &y_orig);

    screenshot = gdk_pixbuf_get_from_drawable (NULL, root_window, NULL,
                                           x_orig, y_orig, 0, 0, width, height);
    return screenshot;
}

Which seems to work perfectly. Thanks!
