html5 - Text drawn in HTML canvas has edges -

-

i draw text "hello world" inside text couple of times inside 'canvas' in html5. outmost text red, next yellow, inside green text, , inner text blue.

what can sharp edges see on letter w?

how can make text render smoothly?

<canvas id="can" width="1200" height="500" dir="ltr">                 <script>                     var can = document.getelementbyid("can");                     var context = can.getcontext("2d");                     context.font = "200px arial";                     context.linewidth = 40;                     context.strokestyle = "red";                     context.stroketext("hello world", 25, 200);                     context.linewidth = 30;                     context.strokestyle = "yellow";                     context.stroketext("hello world", 25, 200);                     context.linewidth = 10;                     context.strokestyle = "lightgreen";                     context.stroketext("hello world", 25, 200);                     context.fillstyle = "blue";                     context.filltext("hello world", 25, 200);                 </script>                 </canvas>
