The GAP 4 package `IntPic' to draw sets of integers         M. Delgado


This is release 0.1 of the package `IntPic'.  The aim of the package is to
help visualising sets of integers and to create publication quality pictures
of these sets. 

There is a manual in the sub-directory 'doc' written using the GAP package
gapdoc which contains several examples illustrating its usage. In particular,
it is illustrated how the pictures produced (either the tizk code or the
pictures in pdf) can b eeasily included in a LaTeX document.

If you have used this package, please let me know by sending me an email. If
you have any suggestion on how to improve it, I would very much appreciate if
you send me an email.

The package shall be distributed with the main GAP archive. In this case, in
order to use it you just have to start GAP and type

      LoadPackage( "intpic" );

For updates between releases of GAP itself or in case it is not distributed
with the main GAP archive, check the package Web page


You may get `IntPic' as a compressed tar archive (file name ends with
.tar.gz). Use the appropriate command on your system to unpack the

On UNIX systems the compressed tar archive may be unpacked by

    tar xzf intpic-<version>.tar.gz

or, if tar on your system does not understand the option z, by

    gunzip intpic-<version>.tar.gz
    tar xf intpic-<version>.tar

which will in each case unpack the code into a directory 'intpic'
in the current directory. We assume that the current directory is the
directory /usr/local/lib/gap4r5/pkg/.


You may have to start GAP with the -l option, for instance,

gap -l "/usr/local/lib/gap4r5"

Then try the following

LoadPackage( "intpic" );

Good luck!
If the load has been successful the package banner will be shown.

If you use a LINUX system, you may want to, in order to save typing, write

in the file `.bashrc' (or something equivalent, maybe with another syntax):

alias gap='gap -l "/usr/local/lib/gap4r5;"'

and in the file `.gap/gaprc'

LoadPackage( "intpic" );


In other systems, there are equivalent ways to do the same.
