[Radiance-general] Create constant radiance image

[David Smith]

This script below may be on the right track. Save it as "pblank", make
it executable, and put it in /usr/bin or wherever. It'll make a X by Y
image with all pixels having value of VALUE. It requires Python to be
installed, by the way.

values of VALUE

echo "print('$3 $3 $3 \n' * $1 * $2)" | python | pvalue -di -d -r -h
