Python Gerber Library

This library provides a simple and elegant parser for Gerber and NC Drill files. It's written in pure Python and supports all Gerber commands, including most deprecated ones.

Example

Setup

pip install python-gerber

Usage

import pygerber.gerber_layer
import pygerber.renderers.svg

pygerber.gerber_layer.GerberLayer()
gl = pygerber.gerber_layer.GerberLayer()
gl.read("<path_to_gerber_file>")

s = pygerber.renderers.svg.SvgLayerRenderer()
s.add_layer(gl)
s.save("<output_path.svg>")
