JPEG Image embedding does not handle EXIF orientation marker

[shinmawa]

Embedding a JPEG into a document does not recognize the EXIF "orientation" value, meaning that if an image is rotated (values 2-8 in the EXIF "orientation" field), the image will be improperly rotated and/or flipped in the resulting document.

I've included an example JPEG with the orientation flag set to 6 as well the resulting PDF document when embedded.
