pcb-tools is currently without a maintainer. Code is provided as is. Check #228 to a list of possible alternatives. PyGerber or other forks of pcb-tools might be what you need.

Tools to handle Gerber and Excellon files in Python.

import gerber
from gerber.render import GerberCairoContext

# Read gerber and Excellon files
top_copper = gerber.read('example.GTL')
nc_drill = gerber.read('example.txt')

# Rendering context
ctx = GerberCairoContext()

# Create SVG image
top_copper.render(ctx)
nc_drill.render(ctx, 'composite.svg')

Source code for this example can be found here.

PCB Tools Documentation

Dependencies for developing and testing pcb-tools are listed in requirements-dev.txt. Use of a virtual environment is strongly recommended.

$ virtualenv venv
$ source venv/bin/activate
(venv)$ pip install -r requirements-dev.txt
(venv)$ pip install -e .

We use pytest to run pcb-tools's suite of unittests and doctests.
