class_docstr: A class that creates a grid of Axes. In matplotlib, the axes
  location (and size) is specified in the normalized figure
  coordinates. This may not be ideal for images that needs to be
  displayed with a given aspect ratio.  For example, displaying
  images of a same size with some fixed padding between them cannot
  be easily done in matplotlib. AxesGrid is used in such case.

      elif mode == "L":
