All,
I am trying to use the EarthImagePlugIn to display an earth image and
then as I zoom in I would like to display a CADRG. I got this to work
using the ScaleFilterLayer class and a shapefile instead of the earth
file but I'm getting an Array Index Out of Bounds Error when I try it
with the Earth Layer. I can display the earth file by itself as well.
Also is the search engine down for searching the archives?? My
properties files looks like this:
# MAP STARTUP PROJECTION PARAMETERS
# Latitude and longitude in decimal degrees
openmap.Latitude=20f
openmap.Longitude=-20f
# Scale: zoom level (1:scale)
openmap.Scale=3000000000f
openmap.Projection=com.bbn.openmap.proj.CADRG
# APPLICATION WINDOW DIMENSIONS
# Width and Height of map, in pixels
openmap.Width=640
openmap.Height=480
# WINDOW STARTUP LOCATION
# pixel X/Y window position (if values < 0, then center the window on
the screen)
openmap.x=-1
openmap.y=-1
openmap.layers=scaledLayers
openmap.startUpLayers=scaledLayers
#ScaledLayers uses the ScaleFilterLayer to switch between layers at
certain scales.
scaledLayers.class=com.bbn.openmap.layer.ScaleFilterLayer
scaledLayers.prettyName=All Layers
#scaledLayers.layers=shapePolitical jrpf
scaledLayers.layers=earthImage jrpf
scaledLayers.transitionScales=10000000

This is the error along with some debugging statements:
