You can fill a region of an image with a reference image instead of a colour. The front, back, or result image can be used as the reference image. The Wash, Shade, Clone, or Reveal media can also be used to perform the fill.

To fill a region with a reference image:

1. Click Fill.

   The Fill controls appear.

4. Select the Special Effects medium you want to use (Clone, Reveal, Wash, or Shade). See Using Special Effects Media.
5. Set the Reference box to Front, Back, Result, or Saved, and set the brush opacity.

   A value of 100% fills the area completely with the reference image.
