In this code snippet, you are using the low level ImageIO classes (the set
of classes providing low level access capabilities to a file).
In case your aim is working on grid coverages and their properties
(Envelope, CoordinateReferenceSystem,...) I suggest to you using the
Geotools classes instead.
A Geotools grid coverage reader is based on a proper ImageIO ImageReader.
(In this specific case the Geotools DTEDReader class is internally based on
the DTEDImageReader class).
Therefore, you should use this code:
------------------------------------------------------------------------------------
File file = .....
DTEDReader reader = new DTEDReader(file);
GridCoverage2D gc = (GridCoverage2D) reader.read(null);
gc.show();
-------------------------------------------------------------------------------------
The gc.show() call will do the trick (rendering your file).

I'm not too familiar with the ImagePane classes. I guess someone on the list
will give you additional help on it.
