Compute isorings and contour polygons (using marching squares algorithm).
A 2D library to trace contours.
A Rust library for 2D geometry: geometric objects, algorithms and visualization
2D polyline/shape library for offsetting, combining, etc.
Generate interactive Fourier epicycle animations from contours, text, or SVG files
Rust crate cv-contour supports ESRI J shapefile
Boolean Operations for 2D Polygons: Supports intersection, union, difference, xor, and self-intersections for all polygon varieties.
Rust crate shape-contour supports ESRI J shapefile (C bindings)
Pure Rust implementation of Minuit-style parameter optimization
C foreign function interface for the cavalier_contours crate
Provides a minimalist layout theme for Contour
Contrek is a Ruby gem with a C++ core for fast contour tracing and edge detection in PNG images. It extracts polygonal contours from bitmap shapes, enabling image processing, shape analysis, and raster-to-vector workflows such as PNG to SVG conversion.
