[IDV #DHS-858869]: Deepwater Horizon and IDV



Hi CJ-

What display type are you using for this?  Jeff has been playing around with a 
point cloud control which might be useful to you.

What are the units in the file?  Can you upload a sample file to:

http://motherlode.ucar.edu/repository/alias/idvupload

?

The file type guessing is based on a filename pattern and the netCDF grid data 
source has .*netCDF.* in the list of patterns.  You can set the type using the 
Data Source Type widget in the file chooser.  That's the best workaround I have 
right now.

Do you want to retain the black background?  If not, there is no automatic way 
of changing the background to white.  You could do that manually using the 
View->Color->Black on White menu.  Otherwise, to save an image, use the 
View->Capture->Image... menu to capture the image.  You can capture just the 
view (black region) or the entire frame.  The default is jpeg, but use .png as 
the extension to create a better quality PNG file.
