\ingroup PS
 
\brief Interface to PDF.
 
Like PostScript, PDF is a vector graphics output format allowing a very high
graphics output quality. The functionalities provided by this class are very
similar to those provided by `TPostScript`.
 
Compare to PostScript output, the PDF files are usually smaller because some
parts of them can be compressed.
 
PDF also allows to define table of contents. This facility can be used in ROOT.
The following example shows how to proceed:
~~~ {.cpp}
{
   TCanvas* canvas = new TCanvas("canvas");
   TH1F* histo = new TH1F("histo","test 1",10,0.,10.);
   histo->SetFillColor(2);
   histo->Fill(2.);
   histo->Draw();
   canvas->Print("plots.pdf(","Title:One bin filled");
   histo->Fill(4.);
   histo->Draw();
   canvas->Print("plots.pdf","Title:Two bins filled");
   histo->Fill(6.);
   histo->Draw();
   canvas->Print("plots.pdf","Title:Three bins filled");
   histo->Fill(8.);
   histo->Draw();
   canvas->Print("plots.pdf","Title:Four bins filled");
   histo->Fill(8.);
   histo->Draw();
   canvas->Print("plots.pdf)","Title:The fourth bin content is 2");
}
~~~
Each character string following the keyword "Title:" makes a new entry in
the table of contents.
