PRINTIM Options

[Jennifer Adams]

Steve,
The documentation is unclear about this -- sorry. The -t and -b options  
were added with version 1.9b4 (or maybe 1.9b3, I don't remember  
exactly). You might be able to achieve what you want using the Image  
Magick routines outside of GrADS (that's what we did before these  
features were built into GrADs...)
