首先自己input file选择的图片readAsDataURL获取到base64的字符串, 再用 binaryajax获取图片的二进制数据(data-url to a binary string). 然后根据二进制数据利用exif.js获取exif信息(主要是exif.Orientation), 再用去重新画图, 再读取新的base64图片

1 是iOS6的bug, 较大的图片可能会发生(大概>2M), 已经有人提交bug给 Apple了(iOS7未测试). 2 是因为相机拍摄的图片本身可能就是反转的, 拍摄的图片里EXIF信息的 orientation记录了图片的转向(取值范围是1/3/6/8, 一般是:1/3/6/8). 默认竖拍的时候其实就是翻转的, 这时的orientation=6(相当于向左转90度, -90deg) .....
