Hi Rob, I'm doing similar things now with Python and PIL. I generate smooth PNGs by creating bigger ones (4*256x4*256) and then resizing with antialised option switched on. It is bit longer process but I'm pre-generating all tiles anyway, so it is not a problem. Also as you've mentioned I do points clustering on smaller zoom levels which buys me some time on tiles generation.
Hope that helps and good luck! ;-) Cheers, Vasily 2009/5/11 Rob Scriva <[email protected]> > > G'day John, > > Basically the zipmap tiles are similar to what I'm generating now. > Ultimately I'm looking to generate polygons that are similar to the > ones generated by the API itself.
