[GRASSLIST:765] p.map.new & rast2gif (in GRASSLinks)

[Hayashi Shin-ichiro]

Dear GRASS Users:

I'trying to install GRASSLinks.

GRASSLinks has "rast2gif" command to convert map file to gif file.
 
rast2gif-----------------------------------------------------

#! /bin/sh
trap "/bin/rm -f $TMP_PATH/grasslinks.$$.ppm"  0 1 2 3 5 9 15

GIF=$1
GRASTER=$2
GVECTOR=$3
GSITES=$4
VCOLOR=$5
SCOLOR=$6
GIF_SIZE=$7
SCRIPT=$TMP_PATH/pmap_script.$$

touch $SCRIPT
p.select ppm > /dev/null 2>&1

if [ $GRASTER != "none" ]
then
        echo "raster $GRASTER" >> $SCRIPT
fi

if [ $GVECTOR != "none" ]
then
        echo "vector $GVECTOR" >> $SCRIPT
        echo "     color $VCOLOR" >> $SCRIPT
        echo "     end" >> $SCRIPT
fi

if [ $GSITES != "none" ]
then
        echo "sites $GSITES" >> $SCRIPT
        echo "     color $SCOLOR" >> $SCRIPT
        echo "     end" >> $SCRIPT
fi

echo "end" >> $SCRIPT

p.map.new input=$SCRIPT  > /dev/null 2>&1

case $GIF_SIZE in
    large)   MAX_RES=800 ;;
    medium) MAX_RES=400 ;;
    small) MAX_RES=200 ;;
esac

( $PBM_PATH/pnmscale -xysize $MAX_RES $MAX_RES < $MAPLP | $PBM_PATH/ppmquant 256
| $PBM_PATH/ppmtogif > $TMP_PATH/$GIF ) 2> /dev/null

-------------------------------------------------------------------

The first half of this script works,(to echo "end" >> $SCRIPT )
Because this script makes "$SCRIPT" file. 
But "p.map.new" command can't make ppm file.
Why can't "p.map.new" command make ppm file?

Please give me your suggestion.

And I have some questions.
1) "p.map.new" command demands parameter "GISBASE" and "GISRC".
    How does GRASSLinks read these parameter?
 
2) In this script, Which does p.map.new use ppm driver?

GRASS has already have PPM driver in /*/grass/etc/paint/driver.sh/ppm .
On the other hand, GRASSLinks has PPM driver in /home/grass/grasslinks/paint/dreiver.sh/ppm .
Which does p.map.new use ppm driver?

Please give me your advise.
Thank you in advance.
Sincerely yours.
