Ghostscript__ is a well known interpreter for the PostScript language and for PDF. This package implements a interface to the Ghostscript C-API__ using ctypes__. Both a low-level and a pythonic, high-level interface are provided.

This package is currently tested only under GNU/Linux. Please report whether it works in your environment, too. Thanks.

Example

Here is an example for how to use the high-level interface of
`python-ghostscript`. This implements a very basic ps2pdf-tool::

  import sys
  import locale
  import ghostscript

  args = [
      "ps2pdf",	# actual value doesn't matter
      "-dNOPAUSE", "-dBATCH", "-dSAFER",
      "-sDEVICE=pdfwrite",
      "-sOutputFile=" + sys.argv[1],
      "-f",  sys.argv[2]
      ]
  ghostscript.Ghostscript(*args)

Here an example for passing a string document to Ghostscript::

  # documents passed to ghostscript need to be bytes
  doc = b"""%!
  /Helvetica findfont 20 scalefont setfont       
  50 50 moveto
  (Hello World) show
  showpage
  quit
  """

  import ghostscript

  args = """test.py
       -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pdfwrite -sOutputFile=/tmp/out.pdf
       """.split()

  with ghostscript.Ghostscript(*args) as gs:
      gs.run_string(doc)

distribution archive.
