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:
Each character string following the keyword "Title:" makes a new entry in the table of contents.

This parameter determines the appearance of joining lines in a PDF output. It takes one argument which may be:
To change the line join behaviour just do:
Set color index for markers.

Write a Real number to the file.
This method overwrites TVirtualPS::WriteReal. Some PDF reader like Acrobat do not work when a PDF file contains reals with exponent. This method writes the real number "z" using the format "%f" instead of the format "%g" when writing it with "%g" generates a number with exponent.
