Output transparent figures

[Stephen R McMillan]

Wang,

Try using the "-t" (transparent) option with printim.  For example,

'printim image.png -t 0' should produce an image with a transparent 
background (assuming background is color 0).

Reference from GrADS Documentation Index:  
http://grads.iges.org/grads/gadoc/gradcomdprintim.html

Note:  I believe the transparent option will work only with versions 1.9 
or later.

Output transparent figures





Hello, 

   Is it possible for GrADS to output transparent figures? E.g. when use 
printim to save the figures,
save it as transparent, so we can use it in Google earth or so.

Thanks
Wang Jun
