在Qt中读取图像的EXIF元数据 [英] Read exif metadata of images in Qt

问题描述

在我的Qt应用程序中，我想读取图像的exif数据. QImage或QPixmap似乎没有提供此类挂钩.

In my Qt app I want to read exif data of images. QImage or QPixmap don't seem to provide such hooks.

Qt中是否有任何API允许在不使用libexif之类的外部库的情况下读取exif?

Is there any API in Qt that allows reading exif without using external libraries like libexif?

这是推荐答案

QImageReader有一个名为transformation()的方法，该方法在5.5版中引入，首先应该尝试一下.

QImageReader has a method named transformation() which is introduced in version 5.5, first you should try that.
