[geotk] applet to display raster

[Ramzi Oueslati]

Thanks Martin.

The TIFF static class is not visible (private I guess). I added the
following line instead:
IIORegistry.getDefaultInstance().registerServiceProvider(
                new GeoTiffImageReader.Spi("TIFF"), ImageReaderSpi.class);

And it works fine. There is some kind of refreshing issue (coverage
shows up and then disappears in the very first seconds) but after I
execute some operations like zoom-in and move then the coverage comes
back and finally sticks there. It also works when launching with java
web start (which used to show the same errors as reported in the
earlier posts).

Trying to display a JPEG coverage still throws the "Envelope"
exception but I guess I understand the underlying logic and I will
figure it out.

Thank you so much for your help.

Regards,
Ramzi Oueslati
