[IDV #IFC-104064]: how to save as tif

Hi  Cynthia-

Thanks for the detailed explanation.  It really helps me figure out
what's going on.

This uses the generic VisAD reader which handles a lot of different formats,
including netCDF.

The OMNI control doesn't have the ability to save off the individual frames.
I was confused and thought you were getting the Quick Time display control.
Sorry for the confusion.

It turns out that the Image format just uses the same reader as the
"I'm Still Feeling Lucky".  So, it's a bit misleading.

Well the problem here is that the Point Data reader is a bit brain dead.
It doesn't report an error until you try to plot something.  I'm in 
the process of fixing that.

This option is only for the main display and not for the Omni control.
My apologies for sending you down the wrong path.

So, the issue is that the IDV doesn't understand your netCDF file except
through the generic reader and the Omni Control has no facility for
capturing frames.

What type of data is this netCDF file (point, grid, something else?).  
What type of display do you want to make out of it?

If the file is really big, can you at least send me a dump of the CDL
(ncdump -h).
