[GEMPAK #RLP-791299]: Using gdthgt with GF



Thanks for the info.

I understand that the GF driver is not producing gif images but the GIf driver 
is.  Is there a reason you can't use the GIF driver? (are you running the 
script from the cron/don't need or have access to the X server?)

Because the GF device is not tied to the X server and does not generate a gplt 
process, it will not display a graphics window and will create a separate file 
for each active frame either when the device is closed or a new file name is 
given. If you're trying to overlay more graphics on the same image (by running 
two instances of gdhght) you'll have to use the GIF driver as the gplt process 
will remain open and the image file will not be written out and saved until the 
gpend command end the process.
