Chrome Image EXIF的直接问题 [英] Chrome Image EXIF Orienation Issue
问题描述
我正在构建一个展示图片的网络应用程序。大多数照片都是由智能手机拍摄的,并具有EXIF旋转信息。
我正在公开一个url,它不会修改就返回图片blob。
I'm building a web app that shows pictures. Most of the pictures were taken by smart phones and have EXIF rotation information. I'm exposing a url which return the image blob without modification.
我注意到当我把这个URL放在img标签中时Chrome并不尊重EXIF的方向数据,但是当我把网址放在Chrome地址栏中时,它会显示一个带有图像的页面,然后它会尊重EXIF的方向。
I've notice that when I put this url in img tag Chrome does not respect the EXIF orientation data but when I put the url in chrome address bar it show a page with the image and then it does respect the EXIF orientation.
对不起,我不能分享图片,我会试着找到另一个我可以分享的例子。
Sorry I can't share the image, I'll try to find another example that I can share.
有没有人注意到这个问题?
Has anyone notice this problem?
推荐答案
导致此行为的原因是,Chrome只有在直接显示在浏览器标签中作为主文档时,才会基于EXIF数据自动旋转图片。
The reason for this behavior is that Chrome auto-rotates pictures based on EXIF data only if they are displayed directly in a browser tab as the main document.
跟踪此实现的相关铬问题如下所示:

The relevant chromium issue that tracked this implementation is the following: https://bugs.chromium.org/p/chromium/issues/detail?id=56845
在未来,Chrome(和其他浏览器)将会允许开发人员为通过带有CSS图像旋转属性的img标签显示的图像启用自动旋转:

In the future, Chrome (and other browsers) will allow developers to enable auto-rotation also for images displayed via img tags with the CSS image-rotation property: https://bugs.chromium.org/p/chromium/issues/detail?id=158753
