html5使用canvas繪制文字特效

    <canvas id=canvas width=500 height=400 style=background-color: yellow;></canvas>
    代碼如下:
    var canvas=document.getelementbyid(canvas);
    var cxt=canvas.getcontext(2d);
    cxt.font=40px 黑體;
    //繪制實(shí)心字
    cxt.fillstyle=red;//填充紅色
    cxt.filltext(hello,思思博士,10,50);
    //繪制空心字
    cxt.strokestyle=red;//紅色邊
    cxt.stroketext(hello,思思博士,10,100);
