    >>> from pycoast import ContourWriterAGG

    >>> img = Image.open('BMNG_clouds_201109181715_areaT2.png')

    >>> proj4_string = '+proj=stere +lon_0=8.00 +lat_0=50.00 +lat_ts=50.00 +ellps=WGS84'

    >>> area_extent = (-3363403.31,-2291879.85,2630596.69,2203620.1)

    >>> area_def = (proj4_string, area_extent)

    >>> cw = ContourWriterAGG('/home/esn/data/gshhs')

    >>> cw.add_coastlines(img, area_def, resolution='l', level=4)

    >>> cw.add_rivers(img, area_def, level=5, outline='blue')

    >>> cw.add_borders(img, area_def, outline=(255, 0, 0))

    >>> img.show()
