# writeTIFFRepresentation(of:to:format:colorSpace:options:)

Renders the image and exports the resulting image data as a file in TIFF format.

## Declaration

```swift
func writeTIFFRepresentation(of image: CIImage, to url: URL, format: CIFormat, colorSpace: CGColorSpace, options: [CIImageRepresentationOption : Any] = [:]) throws
```

## Parameters

- `image`: The image object to render.
- `url`: The file URL at which to write the output TIFF file.
- `format`: The pixel format for the output image.
- `colorSpace`: The color space in which to render the output image. This color space must conform to either the doc://com.apple.documentation/documentation/CoreGraphics/CGColorSpaceModel/rgb or doc://com.apple.documentation/documentation/CoreGraphics/CGColorSpaceModel/monochrome model and must be compatible with the specified pixel format.
- `options`: A dictionary with additional options for export.

## Discussion

Discussion To render an image for export, the image’s contents must not be empty and its extent dimensions must be finite. To export after applying a filter whose output has infinite extent, see the clampedToExtent() method.
