HTML Preparation code:

<canvas id="canvas" width="400" height="400"></canvas>

Script Preparation code:

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext("2d");

var cacheG = document.createElement('canvas');
var cacheD = cacheG.getContext('2d');

cacheG.width = 12;
cacheG.height = 12;

cacheD.beginPath();
cacheD.fillStyle = '#000';
cacheD.arc(6, 6, 6, 0, Math.PI * 1, true);
cacheD.arc(3, 9, 9, 0, Math.PI * 0.4, true);
cacheD.arc(4, 2, 10, 0, Math.PI * 0.9, true);
cacheD.arc(5, 1, 7, 0, Math.PI * 0.3, true);
cacheD.fill();

Tests:

cache
ctx.drawImage(cacheG, 6, 6);
live
ctx.beginPath(); ctx.fillStyle = '#000'; ctx.arc(6, 6, 6, 0, Math.PI * 1, true); ctx.arc(3, 9, 9, 0, Math.PI * 0.4, true); ctx.arc(4, 2, 10, 0, Math.PI * 0.9, true); ctx.arc(5, 1, 7, 0, Math.PI * 0.3, true); ctx.fill();
