Generating circle paths

[phillebaba]

I am trying to generate paths for circles but don't understand how it should be done as the MapService is not exposed. Would I need to use the native methods, and then translate the result to ILatLong?

Microsoft.Maps.SpatialMath.getRegularPolygon

An example is given on the bing maps repo here, is there any similar example?

Hi Phil, thanks for the comment. I'll revert back with some suggestions over the weekend, but generally speaking, yes, you would need to do exactly what you suggest.

I think it would be best to extend angular-maps with a new circle component and then do a new services and model implementation, because for google, a circle is actually a supported primitive, in Bing you have to approximate with a poly. Quite different implementations. It should not be hard, I give that some thought.

Short term, if you are only interested in a Bing specific implementation, you could create a new circle component and model it after the polygon. Inject map service in the constructor to get an instance of the Bing map service. You can then use the LoadModule methods to load the special module and do the calcs like in the example, convert to ILatLong (there is a conversion function in the BingConversions class).

The problem with this is that it would be a Bing only implementation and you'd couple the component with the concrete implementation of the BingMapService (as the load module related methods are implementation specific and not part of the service contract).

Hope that helps....

Thanks, I will take a look at your suggestion when I have time. It is a shame that it is not possible to subclass directives as that would make things a lot easier. Would it not be simpler to just inject the Bing component with does the point calculations in the parent component and then setting the polygon Paths? Alternately implementing the calculations myself.

How much work do you think it would be to do a dual platform solution. Googles solutions seemed a lot smarter but I am required to use Bing for this project.

If you follow the steps outlined above (creating a service, etc) it will be platform independent. I think it would take about a day or two.
