PostScript libraries for Python

• python-ghostscript calls the Ghostscript library through ctypes. Anything the gs command does works from Python: PS to PDF, pages to PNG, text extraction, running PostScript from a string. GPL-3.0 (and Ghostscript is AGPL-3.0).
• Pillow opens .ps and .eps files as images by calling the gs executable, and its PSDraw module writes simple PostScript pages. Good for thumbnails. MIT-CMU (HPND).
• pycairo is the Python binding of cairo. Draw vector graphics and text on a PSSurface to produce multi-page PostScript. LGPL-2.1 or MPL-1.1.

Matplotlib also saves figures as PostScript (fig.savefig("plot.ps")); see Matplotlib for EPS.

• Pillow Pillow opens PostScript files as images through Ghostscript and writes simple PS pages with PSDraw. How to render a PS file to PNG in Python.
• pycairo pycairo is the Python binding of the cairo graphics library. How to install it and write multi-page PostScript files with text and shapes, set page sizes.
• python-ghostscript python-ghostscript is a ctypes interface to the Ghostscript C API. How to install it, convert PostScript to PDF, render PS pages to PNG.
