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:

{
   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.

Initialize the PDF interface.

fname : PDF file name
wtype : PDF workstation type. Not used in the PDF driver. But as TPDF inherits from TVirtualPS it should be kept. Anyway it is not necessary to specify this parameter at creation time because it has a default value (which is ignore in the PDF case).
