Hi Federico,

I downloaded the version 5.02/00 and did tests - everything works fine and the size of saved .gif file
depends on what is drawn in the canvas.

root [0] TCanvas *c1=new TCanvas("c1","c1",1)
root [1] TFile f("hsimple.root")
root [2] hpxpy->Draw()
root [3] c1->SaveAs("canvas.gif")

Info in <TCanvas::Print>: GIF file canvas.gif has been created root [4] .!ls -l canvas.gif
-rw-r--r-- 1 antcheva cg 16623 Aug 3 14:51 canvas.gif root [5] .!~/xv canvas.gif
// I saw the same picture saved in the file

Please check if your settings of ROOTSYS, LD_LIBRARY_PATH are correct.

Cheers, Ilka
