You probably need something like:

	guchar *raw_image;
	gboolean has_alpha;
	gint rowstride, height, width;
	
	raw_image = gdk_pixbuf_get_pixels (pixbuf);
	has_alpha = gdk_pixbuf_get_has_alpha (pixbuf);
	rowstride = gdk_pixbuf_get_rowstride (pixbuf);
	height    = gdk_pixbuf_get_height (pixbuf);
	width     = gdk_pixbuf_get_width (pixbuf);
