# properties

Returns the metadata properties dictionary of the image.

## Declaration

```swift
var properties: [String : Any] { get }
```

## Discussion

Discussion If the CIImage was created from NSURL or NSData then this dictionary is determined by calling CGImageSourceCopyPropertiesAtIndex(). If the CIImage was created with the properties option, then that dictionary is returned. If the CIImage was created by applying CIFilter or CIKernel then the properties of the root inputImage will be returned.
