I have an application where the full WKT representation of double-precision floats is undesirable.
It seems that WKTWriter has an optional, keyword argument to set the "rounding_precision". Great! Just what I need! However... I can't figure out the calling convention; the ".wkt" method of the shapely object is a PROPERTY... so although the "kwargs" is defined, I can't figure out the right Python syntax to USE them. Examples: >>> from shapely.geometry import Polygon >>> p1 = Polygon([(0,0), (10.1, 0), (31./3, 10), (0, 10)]) >>> print p1.wkt POLYGON ((0 0, 10.1 0, 10.33333333333333 10, 0 10, 0 0)) # as expected >>> print p1.wkt(rounding_precision=8) TypeError: 'str' object is not callable # bummer: I'd like to use something this concise >>> from shapely.geos import lgeos, WKTWriter >>> writer = WKTWriter(lgeos, rounding_precision=8) >>> print writer.write(p1) POLYGON ((0 0, 10.1 0, 10.333333 10, 0 10, 0 0)) # this is the result what I want; can it be done without expressly # creating a WKTWriter()? How can I pass the "rounding_precision" kwarg to the property getter? Thanks, Dan
