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 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)

Here an example for passing a string document to Ghostscript:

doc = """%!
/Helvetica findfont 20 scalefont setfont
50 50 moveto
(Hello World) show
showpage
"""

import ghostscript

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

GS = ghostscript.Ghostscript(*args)
try:
    GS.run_string(doc)
finally:
    GS.exit()

More examples can be found in the examples subdirectory of the distribution archive.
