Hi !
I do have some issue writing PDF files including pages with title !
I am getting a TEX file instead of PDF file using the following code, although I mentioned .pdf in the extension :
{
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:My vertex distribution");
histo->Fill(4.);
histo->Draw();
canvas->Print("plots.pdf(","Title:My vertex distribution");
histo->Fill(6.);
histo->Draw();
canvas->Print("plots.pdf(","Title:My vertex distribution");
histo->Fill(8.);
histo->Draw();
canvas->Print("plots.pdf(","Title:My vertex distribution");
histo->Fill(8.);
histo->Draw();
canvas->Print("plots.pdf(","Title:My vertex distribution");
}
My guess is that this title : “My verTEX distribution” is the faulty guy !

Hi,
first, if you really want a multi-page pdf, use TCanvas::SaveAs
, not TCanvas::Print
. Second, you don’t need (
after plots.pdf
everywhere: you need it only for the first page, then you need nothing for the intermediate pages, and finally you need )
for the last page.
Hi Thank you !
The parenthesis were a typo issue !
I took the example from :
https://root.cern.ch/doc/master/classTPDF.html
One might change it then
Nevertheless using SaveAs, it seems that the Title in the bookmark of the PDF is not working anymore. Therefore I am still looking for a solution
I investigated a bit by looking though TPad, and I found a working solution
This is doing the job !
{
TCanvas* canvas = new TCanvas("canvas");
TH1F* histo = new TH1F("histo","test 1",10,0.,10.);
histo->SetFillColor(2);
histo->Fill(2.);
histo->Draw();
TPDF *pdf = new TPDF("plots.pdf");
pdf->On();
pdf->NewPage();
pdf->SetTitle("My Vertex Distribution");
canvas->Paint();
pdf->NewPage();
pdf->SetTitle("My Vertex Distribution");
canvas->Paint();
pdf->NewPage();
pdf->SetTitle("My Vertex Distribution");
canvas->Paint();
gROOT->GetListOfSpecials()->Remove(gVirtualPS);
delete gVirtualPS;
gVirtualPS = 0;
}

I ran the example you referred to. It works perfectly for me.
plots.pdf (20.5 KB)
