[geotk] [Newbie] Image download and polygon drawing

[johann sorel]

Hi everyone,

Thanks theuns for the explications ;)

For WMS you can find what you are need in module coverage/wms in 
geotoolkit-pending.
package :  org/geotoolkit/wms/

You first need to create WMSServer and WMSMapLayer, you can add the 
maplayer in the mapcontext
after liked said theuns.
Thoses classes are not documented I'm sorry about it but they are pretty 
small and easy to understand.
I don't have the source code here or my test applications, olivier 
terral at geomatys is using thoses
classes so he might give you some more details if you need some.

If you just need to make an image without goign throw an awt/swing 
component you can use the
DefaultPortrayalService class.
