[Tilecache] TileCache to TMS URL format

[Tyler Durden]

After taking a look into the OpenLayers source I figured out:

In Python:

def tilecache_to_tms(url, path='cache', layer='base', ext='png'):
    url = url.replace(path, '', 1).strip('/')
    url = url.replace(layer,'', 1).strip('/')
    url = url.replace('.%s' % ext, '', 1).strip('/')
    tokens = [int(t) for t in url.split('/')]
    z = tokens[0]
    x = (tokens[1] * 1000000) + (tokens[2] * 1000) + tokens[3]
    y = (tokens[4] * 1000000) + (tokens[5] * 1000) + tokens[6]
    return '/%s/%s/%s/' % (z, x, y)

>>> url = '/cache/base/10/000/033/127/000/049/665.png'
>>> tilecache_to_tms(url)
'/10/33127/49665/'

Thanks anyway,
Tyler
