Re: Using the ESRI plugin layer and ScaleFilterLayer

Hi François,

I'd use the EsriPlugIn, and configure the PlugInLayer via the
openmap.properties file for the ScaleFilterLayer:

usparks.class=com.bbn.openmap.plugin.PlugInLayer
usparks.prettyName=US Parks
usparks.plugin=com.bbn.openmap.plugin.esri.EsriPlugIn
usparks.plugin.shp=file:///usr/local/openmap/share/data/park/park.shp
usparks.plugin.shx=file:///usr/local/openmap/share/data/park/park.shx
usparks.plugin.dbf=file:///usr/local/openmap/share/data/park/park.dbf
usparks.plugin.lineColor=ff000000
usparks.plugin.fillColor=ffff0000

The EsriLayer is probably going to be phased out, since it does less
than the PlugIn, and sometimes causes confusion.

The ScaleFilterLayer needs to be updated to handle PlugIns, too, as well
as properly manage 1) Layer status events from the active layer and 2)
the palettes from the active layer.

Hope this helps,

Don
