RE: TCanvas creates PDFs with extra blank page ?

Hi,
Do you get the same with the CINT macro ? Which root version are you using ?
On which platform ?
Cheers,

Subject: [ROOT] TCanvas creates PDFs with extra blank page ?

Hi,

I use the TCanvas.Print method with the "[" and "]" syntax to full multipage PDF and PS files from a PyRoot script. i.e.

canvas = TCanvas()

# Open the file

canvas.Print("File.pdf[")

# print some pages (after plotting histograms etc.)
canvas.Print("File.pdf")

# Close the file

canvas.Print("File.pdf]")

I've noticed that if I create a PDF, my preferred format, I always seem to get an unwanted extra blank page at the start of the document. If, on the other hand I create PS files instead, I don't. See as examples

Any ideas why ?
