[gembud] Changing the Background color in GEMPAK

Hello,

 

I've been trying to change the map background to WHITE, however when I edit
the coltbl.xwp file to change black to white, with the white color values,
the map is still black. Is there anything else that needs to be edited?

 

Also.. I have some cords that I put on my map with the custom file to orient
it, because I am not sure how to make GPMAP work with the SPC cords to get
that map to work in NMAP. Is there any file that we need to edit to make the
default map be different?

 

Thanks
