(sorry, previous mail was sent prematurely) Hi,
I have a large amount of data (approx. 100000 points and 5000 rectangles) which I want to display using Delphi and MapX. As of now I've assumed that I could simply create a feature using featurefactory and add it to a temporary layer. This seems however to be very slow. Some profiling reveals that adding 1000 small rectangles to a layer takes ~27 seconds. 98% of the time is spent on the function call "Map1.Layers.Item['Temp Layer'].AddFeature(f, EmptyParam);". Creating the feature as such seem to be quite fast. I'm running it on a P3/1GHz. Is there a smarter (=faster) way to this? I assume there is since I've seen other mapinfo applications which seem pretty fast. Either a quicker to add a feature to a given layer or a better/faster way to add objects (point & rectangles) to mapinfo. Thanks in advance! Best regards // Niklas
