			python-ghostscript 0.4

		A Python-Interface to the Ghostscript
			 C-API using ctypes

:Copyright: GNU Public License v3 (GPLv3)
:Author:  Hartmut Goebel <h.goebel@crazy-compiler.com>
:Homepage: http://bitbucket.org/htgoebel/python-ghostscript
:Download: http://pypi.python.org/pypi/ghostscript

`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.

__ http://www.ghostscript.com/
__ http://docs.python.org/library/ctypes.html

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


Latest Changes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  * Fixed bug: typo in function call name ctypes.util.find_library

  * (Unix) No longer try to load a specific version (version 8) of
    libgs.so

  * Added low-level interface for set_stdio() plus wrappers for
    file handles

  * (win32) Improved search for best Ghostscript installation:
    Consider Aladdin and GNU Ghostscript, too; Check for existence of
    DLL found in registry; take highest version available.

  * Added win32 example-batch file for testing and other
    improvements/fixes on examples an documentation.


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 ghostscript

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

  ghostscript.Ghostscript(*args)
