[geotk] Next step for WMS

[Sam B]

Well, now I tested all with the DefaultPortrayService, but I still get the same distorted picture.... :-(

Here is the code of my TestFrame, the TestPanel class is just a simple JPanel with an overridden paintComponent that does a drawImage.

Does someone have an idea ?

Thanks,

Sam
