[iOS] Image orientation not respected by PickPhotoAsync

duzenko commented 6 years ago

I have three particular images on my iPad that won't keep their orientation when picked. Using an online exif viewer I can see that it is marked as "Rotate 180". However the media plugin does not rotate the output picture.

Image orientation gets reset

Code snippet

                var picture = await CrossMedia.Current.PickPhotoAsync( new PickMediaOptions { CustomPhotoSize = 512 } );

Some more info - It looks like the image that media picker saves internally may be rotated incorrectly before it is returned from PickPhotoAsync

I view the orig image from my photo gallery (taken with ios cam in portrait orientation) in exif viewer and exif orientation is 'rotate 90 CW' and appears correct in the exif viewer preview.
I then step into MediaPickerDelegate code and get the path of the temp file that media picker creates as it does its thing - export the data container for the app (using xcode->devices), and view the image in the same exif viewer - exif data is correct (rotate 90 CW) but image is rotated to the left 90 deg - indicating it is being rotated 90 ccw when it is saved(?)
