A Python module that converts PNG images into SVG line drawings optimized for drawbots.
Blackstripes Python Extensions is a Python module written in C that converts PNG images into SVG line drawings. It solves the problem of generating vector graphics suitable for drawbots, enabling automated plotting or engraving of artistic line art. The module offers three drawing styles—sketchy, crossed, and spiral—each with customizable parameters like line size, color, and scaling.
Artists, makers, and developers working with drawbots, plotters, or engraving machines who need to convert raster images into executable vector line art. It's also suitable for creative coders exploring algorithmic image transformation.
Developers choose Blackstripes for its high-performance C implementation, multiple artistic line-drawing algorithms, and easy-to-use CLI. It's a specialized tool optimized for drawbot workflows, offering precise control over line generation without relying on generic vectorization software.

Written in C, it ensures efficient image processing and SVG generation, making it suitable for daily production use as stated on blackstripes.nl.
Offers three distinct styles—sketchy, crossed, and spiral—each with customizable parameters like nib size and color, providing creative flexibility for drawbot art.
Includes both a Python API for programmatic integration and a CLI tool for quick conversions, demonstrated in the README with code examples and --help usage.
Specifically designed to generate SVG line drawings suitable for plotters and engraving machines, ensuring practical utility in maker workflows.
Only accepts PNG images, requiring additional steps to convert other formats, which can be inconvenient for diverse image sources.
Requires compiling C code via setup.py, which can be error-prone on some platforms and deters users unfamiliar with development tools.
Tested only with Python 2.7 and 3.4, potentially leading to compatibility issues with modern Python versions without community updates.
