Randall, Assuming the WriteImage module is still in OpenDX, you need to use the Render module rather than the Image module (of course you can run the output from Image->Render->WriteImage but this means rendering the data twice; So use Render->Display instead if you want to see the date you're writing. > > I used to do this in the commercial version with the WriteImage > module.
