Class Description

*-*-*-*-*-*-*-*-*-*-*-*-*The  P O S T S C R I P T  class-*-*-*-*-*-*-*-*-*-*
*-*                      ===============================
*-*
*-*   Graphics interface to PostScript.
*-*
*-*  This code was initially developped in the context of HIGZ and PAW
*-*  by Olivier Couet and Pierre Juillot.
*-*  It has been converted to a C++ class by Rene Brun.
*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

TPostScript() : TVirtualPS()
*-*-*-*-*-*-*-*-*-*-*Default PostScript constructor*-*-*-*-*-*-*-*-*-*-*-*-*

TPostScript(const char *fname, Int_t wtype) :TVirtualPS(fname, wtype)
*-*-*-*-*-*-*-*-*-*-*Initialize the PostScript interface*-*-*-*-*-*-*-*-*-*
*-*                  ====================================
*-*
*-*_Input parameters:
*-*
*-*  fname : PostScript file name
*-*  wtype : PostScript workstation type
*-*
*-*
*-*  The possible workstation types are:
*-*     111 ps  Portrait
*-*     112 ps  Landscape
*-*     113 eps
*-*
*-*  The picture below shows fancy text with national accents or
*-*  subscripts and superscripts. This picture has been generated by
*-*  the macro  psexam. 

  

     The two following tables list the correspondance between the typed
     character and its interpretation using the special characters given
     in TPostScript::Text. These tables are screen copies. True and better
     resolution PostScript files can be seen at  psexam, pstable1 and pstable2. 
 The macro  pstable  has been used to generate the two PostScript tables.

*-*
*-* Define the pattern ipat in the current PS file. ipat can vary from
*-* 1 to 25. Together with the pattern, the color (color) in which the
*-* pattern has to be drawn is also required. A pattern is defined in the
*-* current PS file only the first time it is used. Some level 2
*-* Postscript functions are used, so on level 1 printers, patterns will
*-* not work. This is not a big problem because patterns are
*-* defined only if they are used, so if they are not used a PS level 1
*-* file will not be poluted by level 2 features, and in any case the old
*-* patterns used a lot of memory which made them almost unusable on old
*-* level 1 printers. Finally we should say that level 1 devices are
*-* becoming very rare. The official PostScript is now level 3 !
