[geotk] [Newbie] Image download and polygon drawing

[theuns]

HI Sam
I builded a sample application with the guidance of johann sorel.
I mostly uses shapefiles, so my experience with wms server and layers
from the server is very limited.

I am still new with the geotoolkit library, maybe i can point you in the
right direction, i hope.

The widget to display the gis data is JMap2D in the package
org.geotoolkit.gui.swing.go2 in the geotoolkit-pending part like martin
explained previously.

The way it works(as i understand it) is, you build a MapContext.
eg. MapContext context =
MapBuilder.createContext(DefaultGeographicCRS.WGS84);

Then you create a few maplayers (class is MapLayer) that you add the the
context. This context you later on pass on to the JMap2D widget.
eg. mapWidget.getContainer().setContext(context);

Thats to display the maps, then for the drawing part, there is
MapDecoration classes implemented, one to look at is
AbstractGeometryDecoration.

These MapDecoration classes is used like a "invisible overlay" where you
can "draw" your drawings. 

One implementation of the MapDecoration you can have a look at is, the
AreaDecoration in the package
org.geotoolkit.gui.swing.go2.control.information in the display module ,
in the geotoolkit-pending part.

Unfortunatily i have not yet created wms layers in geotoolkit.

Hope this helps.

Regards
Theuns Heydenrych
