Leon Sans by Jongmin Kim
Leon Sans is an amazing font! A geometric sans-serif made entirely in code (javascript) by Jongmin Kim. Each drawing poing has coordinate values which you can modify to create custom shapes, effects or animations.
It allows to manipulate it like a variable font, to change font weight dynamically. But more than that you can create custom animations, effects or shapes in the HTML5 <canvas>
element. He designed the font to celebrate his newborn baby Leon.
Examples
See more examples on the Leon Sans Github repo or on the website at leon-kim.com/examples/
Check out for example the rain effect.
Usage
Download the minified js file in dist folder and include it in your html
<script src="js/leon.js"></script>
Generate LeonSans and draw it in the Canvas element of HTML5.
this.canvas = document.createElement('canvas'); document.body.appendChild(this.canvas); this.ctx = this.canvas.getContext("2d"); this.leon = new LeonSans({ text: 'The quick brown\nfox jumps over\nthe lazy dog', color: ['#000000'], size: 160, weight: 200 }); requestAnimationFrame(animate); function animate(t) { requestAnimationFrame(animate); this.ctx.clearRect(0, 0, document.body.clientWidth, document.body.clientHeight); const x = (document.body.clientWidth - this.leon.rect.w) / 2; const y = (document.body.clientHeight - this.leon.rect.h) / 2; this.leon.position(x, y); this.leon.draw(this.ctx); }
