Rotating pic without using canvas

Hello guys :slight_smile:

Is there any other way how to rotate pic without using canvas? I strongly prefer rotate whole blob file without using canvas or converting to base64string. Especially because canvas do not persist exif information and also rendering base64string picture is slower then cashed blob. Path where is my file stored is e.g. file:///storage/emulated/0/Android/data/com.games4smarts.myApp/cache/1488813641272.jpg
Or is it possible to change only exif orientation information? exif.js and piexif.js does not solved this problem.

Thank you for advice,
Regards Petr
