Hi Larry,
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?
Thanks a lot,
I hadn't even caught that SIDLayer was deprecated in favour of
MrSIDReferencedImage.
Probably the reason why Stefan removed some references to SID Layers in
WMSLayer code.
SIDLayer has probably to be removed then.

Don't now. I personnaly do not wish to spend time to support this
format, but if we (Larry) can
keep it working without too much effort, maybe some users will be happy
to have it.

changes to WMSLayer have affected SIDLayer. The original SIDLayer
was a quick hack that never got the refactoring it deserved. A
common abstract parent is probably the best practice.

since it was incorporated into the last version of vividsolutions
JUMP as MrSIDReferencedImage (which is not descended from
WMSLayer).. Is there some feature of the original class that
isn't in it? The java2xml perhaps doesn't support saving to the
project as well? I would like to test this, but after an hour of
trying I was unable to get a MRSID file to load in OJ. There are
many different wiki pages and readme files that contradict each
other, but I couldn't get any of them to work. I finally resorted
to debug and found the required path for the support executables,
however I got an NPE when I tried to open a SID file at
com.vividsolutions.jump.workbench.imagery.mrsid.MrSIDReferencedImage.getEnvelope(MrSIDReferencedImage.java:98).
This is the version that doesn't depend on WMSLayer so something
else is going on, but I don't have time right now to trace it down.
