Lightweight vector graphics library

Verg

This is a small, simple vector graphics rendering library. Its goal is to be simple to use and easy to embed in existing projects. It doesn't necessarily want to implement a lot of features. Currently supported things are:

• Rendering quadratic and cubic Bézier curves
• Gradients: linear, radial, conic
• Porter-Duff blending

Here are some demos rendered with the library:

The focus is more on the quality of the renderer rather than the number of features it supports. The work is based on Raph Levien's font-rs (more precisely: the line rendering algorithm). Rendering of quadratic Bézier curves is also based on Raph Levien's work: Flattening Quadratic Bézier Curves. Cubics are rendered using De Casteljau subdivision: Piecewise Linear Approximationof Bézier Curves.

Setting up a development environment

You can check scripts/shell.nix (even if you don't use nix) to see the dependencies that are needed (all of them can be gathered with rustup). Unfortunately the shell.nix is clutteret with ghc and latex even though they're not needed for running the examples, they are there because this is my bachelor's thesis at the same time, and I use them for documentation/testing stuff.

To run the project's tests:

cargo test --all-features
