# ImageTranslationAlignmentObservation

Affine transform information that an image-alignment request produces.

```
struct ImageTranslationAlignmentObservation
```

## Overview

This type of observation results from a [`TrackTranslationalImageRegistrationRequest`](/documentation/Vision/TrackTranslationalImageRegistrationRequest), informing the [`alignmentTransform`](/documentation/Vision/ImageTranslationAlignmentObservation/alignmentTransform) performed to align the input images.

## Topics

### Creating an observation

[`init(VNImageTranslationAlignmentObservation)`](/documentation/Vision/ImageTranslationAlignmentObservation/init(_:))

Creates a translation alignment observation.

### Inspecting an observation

[`let alignmentTransform: CGAffineTransform`](/documentation/Vision/ImageTranslationAlignmentObservation/alignmentTransform)

The alignment transform to align the floating image with the reference image.

### Applying a transform

[`func applyTransform(to: CIImage) -> CIImage`](/documentation/Vision/ImageTranslationAlignmentObservation/applyTransform(to:))

Applies the transform to an image.
