# VTPixelRotationSession

An object that rotates source pixel buffers to destination pixel buffers.

## Overview

Overview To create a rotation session, call VTPixelRotationSessionCreate(_:_:). Optionally configure the session by calling VTSessionSetProperty(_:key:value:). To transfer pixels call VTPixelRotationSessionRotateImage(_:_:_:). When you’re done with the session, call CFRelease to tear it down and release your object reference.
