如何从文件（图像）获取详细信息（属性）。 [英] How can I get details(properties) from file(image).

问题描述

我是Angular 2+的新手，当用户从UI上传图像文件时，尝试检索细节或优先级。标题，评论，作者，相机细节等属性是否有GPS Latlong？等等。



请帮帮我。谢谢



我尝试过：

Hi,

Please help me. Thanks

What I have tried:

var name = event.target.files[i].name;
var type = event.target.files[i].type;
var size = event.target.files[i].size;
var modifiedDate = event.target.files[i].lastModifiedDate;

问题是，除了它之外无法找到其他属性。喜欢标题，评论，作者，相机细节，它有GPS Latlong吗？等等。

the problem is, unable to found other properties apart from it. like Title, comment, author, camera details and does it has GPS Latlong? and etc.

你要找的是EXIF数据： EXIF数据说明|摄影疯狂 [ ^ ]
