I tryed it before, but end up with  segmentation fault:
... I thought the libary get thw width and height from the image itself
...

  GdkImlibImage *gimg;
  gimg =
gdk_imlib_load_image("/home/zahl/C++/dsp/develop/Gxsm/src/xxsmlogo.xpm");
  GnomeCanvasItem *item2 = gnome_canvas_item_new(gnome_canvas_root(
GNOME_CANVAS(area)),
 						 GNOME_TYPE_CANVAS_IMAGE,
						 "image", gimg,
						 "x", 20.0,
						 "y", 20.0,
						 "width", gimg->rgb_width,
						 "height", gimg->rgb_height,
						 //"anchor", GTK_ANCHOR_NORTH_WEST,
						 NULL);

Do you know if it should work as I wrote above ?
Is there a default for "anchor" ?
