ps_get_parameter — Gets certain parameters
Gets several parameters which were directly set by ps_set_parameter() or indirectly by one of the other functions. Parameters are by definition string values. This function cannot be used to retrieve resources which were also set by ps_set_parameter().
   The parameter name can have the following values.
  
fontname
       The name of the currently active font or the font whose
       identifier is passed in parameter modifier.

scopeThe current drawing scope. Can be object, document, null, page, pattern, path, template, prolog, font, glyph.
ligaturedisolvecharThe character which dissolves a ligature. If your are using a font which contains the ligature `ff' and `|' is the char to dissolve the ligature, then `f|f' will result in two `f' instead of the ligature `ff'.
imageencoding
       The encoding used for encoding images. Can be either
       hex or 85. hex encoding
       uses two bytes in the postscript file each byte in the image.
