Re: Strange screenshots problem

[Matt Aylward]

Or, for something completely different, (for grey-scale at least)
I use a int2DFiler to save the state of the Discrete2d or Grid2d to a file
for statistical and fractal analysis. The addition of a three line header to
the ascii file:
---------
P2 
xsize ysize
maximum-value
-----------
and the file becomes a portable grey map. In my case the size and max-value are
constant so the header is identical. Thus in bash and the header lines in
"header"

for x in *.dat
do
cat header $x > ${x%%.dat}.pgm 
done

converts all the integer dumps to pgms without affecting the dat files.
There are many (more) ways to skin a cat (depending if the cat is black & white
or colour)
Cheers,
Matt
