Custom roundRect
function roundRect(canvas, x, y, w, h, r) { if (w < 2 * r) r = Math.round(w / 2); if (h < 2 * r) r = Math.round(h / 2); canvas.beginPath(); canvas.moveTo(x + r, y); canvas.arcTo(x + w, y, x + w, y + h, r); canvas.arcTo(x + w, y + h, x, y + h, r); canvas.arcTo(x, y + h, x, y, r); canvas.arcTo(x, y, x + w, y, r); canvas.closePath(); } roundRect(ctx, 10, 10, 200, 100, 20);
roundRect
ctx.beginPath(); ctx.roundRect(10, 10, 200, 100, 20); ctx.stroke();
rect
ctx.beginPath(); ctx.rect(10, 10, 200, 100); ctx.stroke();
