RE: Print divided canvas

Sorry but I don't understand what you mean!

A similar problem appears with ".jpg" extention but in a tricky way! If I run ".x CanvasTest.C" once (the code below) I get a jpg of the background ... if I run it again (without restarting ROOT) I get the correct output.

TCanvas *canvas;
TH1F *h;

void CanvasTest()
{
  h = new TH1F("hist", "Histo", 10, 0., 10.);   canvas = new TCanvas("canv", "Canvas", 0, 0, 800, 400);   canvas->Divide(2, 1);
  canvas->cd(1);
  h->Draw();
  gPad->Print("puppa1.C");
  canvas->cd(2);
  h->Draw();
  gPad->Print("puppa2.C");
  canvas->cd(0);
  canvas->Print("puppa.jpg");
}

Bye...
