Question

我有一个使用谷歌地图ip v3显示车辆行程的div。我正在使用html2canvas http://html2canvas.hertzen.com。它工作正常，但如果你放大地图就失败了

html2canvas: Renderer: Canvas renderer done - returning canvas obj
html2canvas: Preload starts: finding background-images
html2canvas: Preload: Finding images
html2canvas: Preload: Done.
html2canvas: start: images: 1 / 35 (failed: 0)
html2canvas: start: images: 2 / 35 (failed: 0)
.
.
html2canvas: start: images: 30 / 35 (failed: 0)
html2canvas: start: images: 31 / 35 (failed: 0)

或者有时这是发生的事情。（抱歉，我的声誉不到十，所以我无法上传图片）

放大（从浏览器打印屏幕）

输出html2canvas

这是我的代码：

function printme(){
    html2canvas($('#maincontent'), {
        proxy: "server.js",
        useCORS: true,
        logging: true,
  onrendered: function(canvas) {
    var imgString = canvas.toDataURL('image/png');
      var mywindow = window.open('', 'my div', 'height=400,width=600');
        mywindow.document.write('<html><head><title>my div</title>');
   href="main.css" type="text/css" />');
        mywindow.document.write('</head><body >');
        mywindow.document.write("<img src='"+imgString+"'/>");
        mywindow.document.write('</body></html>');
  }
});

    }
