I've just been sorting out plotting some transformed map data - in this case plotting data on a globe as would be viewed from space. After writing a transform class I realised that there is no void* parameter to pass transform data to plmap and no void * parameter of mapform. Am I missing a way to be able to do this?
It would certainly be useful in the same way as for other transforms. In the scenario above there are obvious benefits to having such a feature as I'd be able to create a generic transform and be able to pass a class or struct containing details about the satellite position.
But I guess this is an API change, unless anyone would be happy to have a second version of the function with different parameters.
