# imageTypes

Returns an array of UTI strings identifying the image types supported by the registered image representation objects, either directly or through a user-installed filter service.

## Declaration

```swift
class var imageTypes: [String] { get }
```

## Return Value

Return Value An array of NSString objects, each of which contains a UTI identifying a supported image type. Some sample image-related UTI strings include “public.image”, “public.jpeg”, and “public.tiff”. For a list of supported types, see UTCoreTypes.h.

## Discussion

Discussion The returned list includes UTIs all file types supported by registered subclasses of NSImageRep plus those that can be converted to a supported type by a user-installed filter service. You can use the returned UTI strings with any method that supports UTIs. Do not override this method directly. If your app supports custom image types, create and register an NSImageRep subclass that handles those types.
