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.
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, "-c", ".setpdfwrite", "-f", sys.argv ] # arguments have to be bytes, encode them encoding = locale.getpreferredencoding() args = [a.encode(encoding) for a in args] ghostscript.Ghostscript(*args)
Here an example for passing a string document to Ghostscript:
doc = b"""%! /Helvetica findfont 20 scalefont setfont 50 50 moveto (Hello World) show showpage quit """ import ghostscript args = b"""test.py -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pdfwrite -sOutputFile=/tmp/out.pdf -c .setpdfwrite""".split() with ghostscript.Ghostscript(*args) as gs: gs.run_string(doc)
More examples can be found in the examples subdirectory of the distribution archive.
