Fabio, For animations or drawing, I believe the only thing that will give you what you need is a GUI app. For that, you should check out GTK+, wxWidgets, or Prima. The first two have Perl bindings but can be a headache to install. The third is cross-platform and is distributed on CPAN, so if you have the X11 development libraries installed, it should Just Work.
Bonus for using Prima: I'll be releasing a plotting library for it in the coming month. :-D David On Mon, Jan 23, 2012 at 3:38 AM, Fabio D'Alfonso < [email protected]> wrote: > Hi, > thanks for you tip. > > I would really be able to write on screen, showing the pencil progress, so > this is probably not the way I would.
