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 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.
