# PHImageContentMode

Options for fitting an image’s aspect ratio to a requested size, used by the [`requestImage(for:targetSize:contentMode:options:resultHandler:)`](/documentation/Photos/PHImageManager/requestImage(for:targetSize:contentMode:options:resultHandler:)) method.

```
enum PHImageContentMode
```

## Overview

With either option, the resulting image may not exactly match the target size, depending on the [`deliveryMode`](/documentation/Photos/PHImageRequestOptions/deliveryMode) and [`resizeMode`](/documentation/Photos/PHImageRequestOptions/resizeMode) properties of the image request. To serve your request more quickly, Photos may provide a slightly larger image—one that it can generate more easily or one that is already cached.

## Topics
