Re: 20030924:GEMPAK GIF white background

Donna,

Apologies for sending you down an arduous path...

The best and easiest way to achieve this is to edit:
/home/gempak/GEMPAK6/gempak/tables/colors/coltbl.xwp

(jweber) lenny:/home/gempak/GEMPAK6/gempak/tables/colors 27 % m coltbl.xwp
! COLTBL.XWP

and put:

as the first entry.

You could re-name this file coltbl.xwp_white

and it should look like this:

coltbl.xwp_white

WHITE           WHI    255    255    255  white


and then call coltbl.xwp_white explicitly in yor GEMPAK routine.

Depending on your use, it may be easier to just edit the existing, and
then edit back..your call.

Please let me know if this works for you..I tested here and had success.

Cheers,

Jeff
