This is a Python command-line script that can parse Altium schematic (*.SchDoc) files, convert them to SVG images, or display them in a window. It is incomplete and there are probably many schematic elements and settings that it does not (yet) understand.

The schematic file format has been documented somewhat in format.md.

You can redistribute and modify this program under the terms of the Do What The Fuck You Want To Public License (WTFPL) version 2, as published by Sam Hocevar. See the COPYING file for details.

• Python 3, from https://www.python.org/
• The OleFileIO library. Version 2.4+ of the Pillow fork, from http://python-pillow.github.io/, is recommended. If a schematic contains bitmap images, Pillow is also needed to display the schematic in a window. You can also use version 0.30 of the OleFileIO_PL fork, from http://www.decalage.info/python/olefileio, if Pillow is not needed.
• TK (Only required to display schematics in a window)

Conversion to SVG:

python3 altium.py schematic.SchDoc > output.svg

Display in a window:

python3 altium.py --renderer tk schematic.SchDoc
