Canvas入门实例05：画一个衣架

本文综合前面的几个例子，画一个晾衣架。

function drawScreen(){      var context = theCanvas.getContext('2d');      context.strokeStyle = 'black';      context.lineWidth = 5;      context.beginPath();      context.moveTo(150,130);      context.lineTo(50,150);      context.arc(50, 175, 25, 1.5*Math.PI, 0.5*Math.PI, true);      context.moveTo(50,200);      context.lineTo(250,200);      context.arc(250, 175, 25, 0.5*Math.PI, 1.5*Math.PI, true);      context.moveTo(250,150);      context.lineTo(150,130);      context.lineTo(150,60);      context.lineJoin = 'round';      context.arc(150, 40, 20, 0.5*Math.PI, Math.PI, true);      context.stroke();      context.closePath();}
