Re: Renderer like Esri

Hi Mitxelko,

For this specific rendering requirements, you'll probably have to make
some modifications to the code. They aren't difficult. I'd modifiy the
EsriPlugIn if I were you.

You could modify the EsriPointList to create Location objects instead of
OMPoint objects, or something like that.

You'll have to use the DbfTableModel object to find attributes for each
graphic, so you can decide how to render it.

That seems to be a java question. If java can find it on the system,
you should be able to use it on the map.

That's another modification you'd have to make to the plugin.

Hope this helps,
