Re: [ROOT] Problem saving canvas as pdf - Mac problem?

Dear Olivier

Starting "root -n" results in the same problem.
Maybe, this problem is Mac-specific, so running the macro on a Mac
should reproduce the problem. As I have mentioned, this problem
appears only after adding the line "gStyle->SetPalette(1,0)".

Best regards
