HI folks, What's the fastest way to convert a numpy array to tuples?
Unfortunately, not all packages take arbitrary sequences when they are expecting a list of tuples. In this case, I'm using PIL's ImageDraw, and want to do: draw.line(points) (points is an Nx2 numpy array of ints) but if I pass in an array, I get, oddly enough, nothing. NO error, just nothing drawn. if I do: draw.line(points.tolist()) SystemError: new style getargs format but argument is not a tuple So I seem to need tuples. This works: draw.line([tuple(p) for p in points.tolist()]) but that seems like it would be slower than it should be (to be honest, not profiled). Is there a faster way? Maybe numpy should have a ndarray.totuple() method. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
