OK, I've located the problem that was causing the NPE. The MRSID
executables now depend on the geos.dll (C++ port of the Java Topology
Suite) which must be located in the same directory. MRSID files now work
fine, although not as well as in SkyJUMP. ;-) (SkyJUMP has added a simple
plugin called EditMrSID which allows adjustment of dynamic range and
transparancy.) I can't see a reason to keep the SIDLayer class. Does
anyone else?
