How to copy Exif data from one image to another?

Question

In Xamarin Forms I take a picture. At this point it has Exif information.
Then I need to rotate it and reduce it's size. Now it has lost most of it's Exif information.

Is there a way in Xamarin Forms to read the Exif data from the original image and copy most of it to the final image? Can it be done without resorting to native code?

Thanks!

Hello,​

No, I cannot Forms Api to read the Exif data. But I found the native platform Api to get/set Exif data.

For Android, you can get/set Exif data by Android.Media.ExifInterface Api

For iOS, you can use kCGImagePropertyExifDictionary to achieve it.
