# Rotate Transformation Engine

The rotate transformation engine rotates images. You can use it to rotate ingested images before analysis, or to rotate images that have been analyzed so that detected faces and text appear in the correct orientation when images are encoded.

The engine also translates any coordinates contained in records, so that their position is correct for the rotated image. For example, face detection outputs the locations of a person's eyes. The co-ordinates are modified so that the positions are correct for the rotated image.

Configuration Parameter | Description
--- | ---
Angle | The rotation to apply to the input image, in degrees, clockwise.
Input | The name of the track that contains the images to rotate.
LuaLine | A Lua script that returns the rotation to apply to the input image, in degrees, clockwise.
LuaScript | A Lua script that returns the rotation to apply to the input image, in degrees, clockwise.
Type | The type of transformation engine to use. Set this parameter to `Rotate`.

This transformation engine produces a single output track, named `taskName.Output`, where `taskName` is the name of the transformation task.
