Hello Rene,

> You did not read my mail carefully.

Yes, I did read and quote your message.

This is why I suggest to replace there non-standard "gifsicle" with the "standard" "convert". "convert" does all jobs the "gifsicle" does . In addition, it can work with many different input formats

I.e. one can convert let's say "*.png" file to animated "gif" too

                          convert *.png anim.gif

Simply compare the capabilities:
http://www.imagemagick.org/script/command-line-options.php vs
http://www.lcdf.org/~eddietwo/gifsicle/man.html

Usually one can find "convert" pre-installed. I.e. it is a "standard" component of Linux. See for example CERN LXPLUS cluster. In the other words, one is not required to download and install it. I found no "gifsicle" program at RCF (http://www.rhic.bnl.gov/RCF/) either. "convert" is there though.

Hope this helps, Valeri

Valeri,

You did not read my mail carefully. The tutorial hsumanim.C uses gifsicle/gifview,
including the instructions to install these two utilities.
