To Michael Foland and Hunter Outten:
Perhaps you are doing this already, but be sure you are following this
procedure to change the background from black to white for the xw, gf,
gif, png drivers. As others have mentioned, you do have to be sure you
don't already have any GEMPAK plotting (gplt) or device driver (xw, gf,
ps, etc . . .) processes running by typing "gpend" at the command prompt.
------------------------------------------------
For on-screen graphics using the /xw/ driver, and for all devices save
PostScript, the default background color is *black*. Note that the
background color is the /first color listed /in the GEMPAK color table
(coltbl.xwp). To change this color to /white/, we avail ourselves of the
very useful convention that GEMPAK uses when it opens any /table file,
/such as a color table. A set of default GEMPAK tables lives in the
$NAWIPS/gempak/tables directory. However, by design, GEMPAK will /first
/look in the user's /current working directory/ when it needs to read
from a table file. This provides an easy way for you to customize any
GEMPAK table file, and changing the GEMPAK color table is one of the
most common local customizations that one can do.
So in your current working directory, create a /link/ to the "white
background" GEMPAK color table, whose file name is
$GEMTBL/colors/coltbl.xwp_white. If you already have /coltbl.xwp/ in
your current working directory, remove it. Then, link to the
/coltbl.xwp_white/ file such that the local file name is /coltbl.xwp/.
ln -s $GEMTBL/colors/coltbl.xwp_white coltbl.xwp
This will ensure that the /background color, /"color 101" is white.
Additionally, the order of colors 31 and 32 (the last two colors in
the table) are reversed.
Remember that this custom color table will only apply when you are
already cd'd into the directory that houses the custom table! If you
wanted to make the white background the default for all directories, you
would need to place it in the $GEMTBL/colors directory.
-------------------------------------------------------
Hope this helps . . .

hey for some reason gpend is not responding to commands and not
opening. Every possible solution to change the NMAP background to
white isnt working. even taking black out of the equation in the
COLTBL.tbl any help on getting this to work?
