Thanks, Jim. That's very useful. I'll code it up and see if I can get everything to work.
Best,
Tamlin

At the top of the documentation page for IDLffMrSID, there's a link for "IDL Feature Support". Unless you're running the 32-bit IDL executable (or an IDL_IDLBridge) on Windows, you'll be out of luck, assuming the documentation is up-to-date.
Here's a handy trick to access to access 32-bit-only functionality from a 64-bit Windows IDL process. This comes in handy for accessing DXF files as well.
IDL> b = idl_idlbridge(ops=32)
% Loaded DLM: IDL_IDLBRIDGE.
IDL> b->execute, 'o = obj_new("idlffmrsid", filepath(subdir=["examples", "data"], "test_gs.sid"))'
IDL> b->execute, 'data = o->getimagedata(level=3)'
IDL> d=b->getvar('data')
IDL> help, d
D BYTE = Array[1, 64, 64]

Glad to know I'm not crazy. Sounds like I may be sending my second support request to Exelis in the last 2 days. . . hopefully this one turns out as well as the last one did.

Same results on my Windows 7 and LINUX machines running IDL 8.2.1.
