The orientation of the input image (counter-clockwise direction). If your
application displays the image, you can use this value to correct image
orientation. The bounding box coordinates returned in
FaceDetails
represent face locations before the image
orientation is corrected.
If the input image is in .jpeg format, it might contain exchangeable
image (Exif) metadata that includes the image's orientation. If so, and
the Exif metadata for the input image populates the orientation field,
the value of OrientationCorrection
is null and the
FaceDetails
bounding box coordinates represent face
locations after Exif metadata is used to correct the image orientation.
Images in .png format don't contain Exif metadata.
