Oziexplorer .map file generation while exporting large map picture

[GoogleCodeExporter]

Based on Nik4 (https://github.com/Zverik/Nik4), I suggest adding a new feature 
to make the generated large PNG files directly in Oziexplorer, by adding these 
(or similar) code lines to the maps.py file.


def prepare_ozi(minx, miny, maxx, maxy, mwidth, mheight, name):
    """Create georeferencing file for OziExplorer"""
    def deg(value, is_lon):
        degrees = math.floor(abs(value))
        minutes = (abs(value) - degrees) * 60
        return '{:4d},{:3.5F},{}'.format(int(round(degrees)), minutes, ('W' if is_lon else 'S') if value < 0 else ('E' if is_lon else 'N'))
    points = "\n".join(['Point{:02d},xy,     ,     ,in, deg,    ,        ,N,    ,        ,E, grid,   ,           ,           ,N'.format(n) for n in range(3,31)])
    return '''OziExplorer Map Data File Version 2.2
