[GRASSLIST:766] Re: p.map.new & rast2gif (in GRASSLinks)

[Xueming Wu]

Hi,

If your GRASSLINKS can create pmap_script.$$ but can't create gif,
you need to check the followings are correct:

1. if p.map.new generates ppm file. p.map.new will create a
file named paint.ppm. And the direcotry of paint.ppm is defined
in grass5/etc/paint/driver.sh/ppm by MAPLP.

2. if ppmtogif works. ppmtogif is a tool of unix/lunix. It read
the paiint.ppm and convert it into gif. So, please make sure
setup for directory is correct.

The setup for GISBASE and GISDBASE  is done in one of GRASSLINKS
funtion.

Regards,

Xueming
