Create graphics with a hand-drawn, sketchy, appearance

Rough.js

Rough.js is a small (\<9 kB) graphics library that lets you draw in a sketchy, hand-drawn-like, style. The library defines primitives to draw lines, curves, arcs, polygons, circles, and ellipses. It also supports drawing SVG paths.

Rough.js works with both Canvas and SVG.

Usage

Rough.js rectangle

const rc = rough.canvas(document.getElementById('canvas'));
rc.rectangle(10, 10, 200, 200); // x, y, width, height

or SVG

const rc = rough.svg(svg);
let node = rc.rectangle(10, 10, 200, 200); // x, y, width, height
svg.appendChild(node);

Lines and Ellipses

Rough.js rectangle

rc.circle(80, 120, 50); // centerX, centerY, diameter
rc.ellipse(300, 100, 150, 80); // centerX, centerY, width, height
rc.line(80, 120, 300, 100); // x1, y1, x2, y2

Filling

Rough.js rectangle

rc.circle(50, 50, 80, { fill: 'red' }); // fill with red hachure
rc.rectangle(120, 15, 80, 80, { fill: 'red' });
rc.circle(50, 150, 80, {
  fill: "rgb(10,150,10)",
  fillWeight: 3 // thicker lines for hachure
});
rc.rectangle(220, 15, 80, 80, {
  fill: 'red',
  hachureAngle: 60, // angle of hachure,
  hachureGap: 8
});
rc.rectangle(120, 105, 80, 80, {
  fill: 'rgba(255,0,200,0.2)',
  fillStyle: 'solid' // solid fill
});

Fill styles can be: hachure(default), solid, zigzag, cross-hatch, dots, dashed, or zigzag-line

Sketching style

Rough.js rectangle

rc.rectangle(15, 15, 80, 80, { roughness: 0.5, fill: 'red' });
rc.rectangle(120, 15, 80, 80, { roughness: 2.8, fill: 'blue' });
rc.rectangle(220, 15, 80, 80, { bowing: 6, stroke: 'green', strokeWidth: 3 });

SVG Paths

Rough.js paths

rc.path('M80 80 A 45 45, 0, 0, 0, 125 125 L 125 80 Z', { fill: 'green' });
rc.path('M230 80 A 45 45, 0, 1, 0, 275 125 L 275 80 Z', { fill: 'purple' });
rc.path('M80 230 A 45 45, 0, 0, 1, 125 275 L 125 230 Z', { fill: 'red' });
rc.path('M230 230 A 45 45, 0, 1, 1, 275 275 L 275 230 Z', { fill: 'blue' });
