C src code

see this static image for code for one image.

Here is the code for sequence of images :

Bash and Image Magic src code

Convert sequence of pgm images into animated gif ( with text label )

#!/bin/bash

# script file for BASH 
# which bash
# save this file as g
# chmod +x g
# ./g

# for all pgm files in this directory
for file in *.pgm ; do
  # b is name of file without extension
  b=$(basename $file .pgm)
  # convert from pgm to gif and add text ( level ) using ImageMagic
  convert $file -pointsize 100 -annotate +10+100 $b ${b}.gif
  echo $file
done

# convert gif files to animated gif
convert -delay 100   -loop 0 %d.gif[0-24] a24.gif

echo OK
# end

It was to big ( > 12.5MP limit ) :

convert a24.gif -resize 750x550 a24s.gif

New file is up to 100 level and is still > 12.5 MP limit but smaller would be not good.
