## Class Description

     TPDF

     Graphics interface to PDF.

TPDF() : TVirtualPS()

     Default PDF constructor

TPDF(const char *fname, Int_t wtype) : TVirtualPS(fname, wtype)

     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).

~TPDF()

     Default PDF destructor

void CellArrayBegin(Int_t, Int_t, Double_t, Double_t, Double_t, Double_t)

     Draw a Frame around a box

     mode = -1  box looks as it is behind the screen
     mode =  1  box looks as it is in front of the screen
     border is the border size in already precomputed PostScript units
     dark  is the color for the dark part of the frame
     light is the color for the light part of the frame

         according to the current transformation.
      If NN>0 the line is clipped as a line.
      If NN<0 the line is clipped as a fill area.

void DrawPolyLineNDC(Int_t nn, TPoints *xy)

     Draw a PolyLine in NDC space

      Draw a polyline through  the points  xy.
      If NN=1 moves only to point x,y.
      If NN=0 the x,y are  written  in the PDF        file
         according to the current transformation.
      If NN>0 the line is clipped as a line.
      If NN<0 the line is clipped as a fill area.

      If nn=0 the XW(1) and YW(1) are  written  in the PostScript file
              according to the current NT.
      If nn>0 the line is clipped as a line.
      If nn<0 the line is clipped as a fill area.
