NanoVG Rust wrapper

Now with Cargo!

This is a Rust-language wrapper for the NanoVG vector graphics library.

NanoVG is written in C, and it supports several back-ends: GL2, GL3, GLES...

NanoVG is not an extremely complete or extensive implementation of vector graphics. It is however small and hardware-accelerated, which is what I want.

Prerequisites

This build process will produce a Rust library, which includes the Rust wrapper for nanovg functions, and which statically links in those functions. NanoVG only does the graphics drawing, though; you'll need to be getting a GL context from somewhere. The examples use GLFW.

Examples require GLFW3 to be installed.

Building

Build using Cargo:

git clone --recursive https://github.com/KevinKelley/nanovg-rs
cd nanovg-rs
cargo build

To build the demo, then:

cd examples/demo
cargo build
./target/debug/example

Note that font and image resources won't be found if you run from inside the target directory.

In the demo,

• 'p' switches between pre- and un-premultiplied alpha;
• 's' saves a screenshot;
• and 'space' toggles scale/rotate of the pseudo-window stuff.

Usage

Add the following to Cargo.toml:

[dependencies.nanovg]
version = "*"
features = ["glX"]

where glX should be exactly one of gl2, gl3, gles2 or gles3, to specify the version of OpenGL for which NanoVG should be built.
