# serializedXMP(from:inputImageExtent:)

Serializes filter parameters into XMP form that is suitable for embedding in an image.

## Declaration

```swift
class func serializedXMP(from filters: [CIFilter], inputImageExtent extent: CGRect) -> Data?
```

## Parameters

- `filters`: The array of filters to serialize. See Discussion for the filters that can be serialized.
- `extent`: The extent of the input image to the filter.

## Discussion

Discussion At this time the only filters classes that can be serialized using this method are, CIAffineTransform, CICrop, and the filters returned by the CIImage methods autoAdjustmentFilters() and autoAdjustmentFilters(options:). The parameters of other filter classes will not be serialized.
