# tiffRepresentation

A TIFF representation of the bitmap image data.

```
var tiffRepresentation: Data? { get }
```

## Discussion

Accessing this property results in a call to the [`tiffRepresentation(using:factor:)`](/documentation/AppKit/NSBitmapImageRep/tiffRepresentation(using:factor:)) method using the stored compression type and factor retrieved from the initial image data or changed using the [`setCompression(_:factor:)`](/documentation/AppKit/NSBitmapImageRep/setCompression(_:factor:)) method. If the stored compression type isn’t supported for writing TIFF data (for example, [`NSBitmapImageRep.TIFFCompression.next`](/documentation/AppKit/NSBitmapImageRep/TIFFCompression/next)), the stored compression is changed to [`NSBitmapImageRep.TIFFCompression.none`](/documentation/AppKit/NSBitmapImageRep/TIFFCompression/none) before calling the [`tiffRepresentation(using:factor:)`](/documentation/AppKit/NSBitmapImageRep/tiffRepresentation(using:factor:)) method using the compression that’s returned by [`getCompression(_:factor:)`](/documentation/AppKit/NSBitmapImageRep/getCompression(_:factor:)) (if applicable).

If a problem is encountered during generation of the TIFF, an [`NSTIFFException`](/documentation/AppKit/NSTIFFException) or an [`NSBadBitmapParametersException`](/documentation/AppKit/NSBadBitmapParametersException) is raised.
