结果应该是什么

http://example.com/600x400/000/fff

Javascript代码

for (var i=0; i<options.amount; i++) {

        drawImage(ctx, options);
        var $_newImageContainer = $('<div />');
        var $_newImage = $('<img />');
        var imgData = $_canvas[0].toDataURL('data:image/png;base64,iVBORw0K...');       
        $_newImage.attr('src', imgData).appendTo('#output');
        images.push(imgData);

        var nov_canvas = imgData;
        var nov_popup = window.open(imgData);
    }

我想要实现的目标，可以在这里更好地看到：https://dummyimage.com/

我的代码

https://jsfiddle.net/eLk78kL5/

PS：我不知道为什么jsfiddle代码不起作用，因为相同的代码在本地工作...

最后一个问题：是否可以获得正常的图片网址，在本地运行？

将base64网址转换为图片网址
