zcanvas

A cross platform HTML Canvas implementation in Zig.

The pure Zig canvas backend is a work in progress and is far from complete and has poor performance. Alternatively there is the Cairo backend which is faster and more complete at the cost of being more heavyweight and relying on C which requires linking the C standard library.

Install Dependencies

sudo apt-get install libsdl2-dev
sudo apt-get install libcairo2-dev

Build Demo

This project uses the jvbuild build system. Use jvbuild run demo to run example usage code.

Rendering Output

zcanvas provides a window library based on SDL2 for rendering output to a desktop window and handling input.

API

The JS wrapper has the same API as a real HTML canvas context. The Zig version of the library due to being a staticly typed language has a few differences for example instead of ctx.fillStyle = "#ffffff" you must use ctx.fillStyle = [_]u8{255, 255, 255, 255} instead. Read docs.md to view full Zig API.

Shout out

Check out NoBS Code on YouTube. They taught me the math required to render shapes.
