The Output composition selects how the output of this filter will be determined. There are three choices:

  • Shadow plus image will output both the input image and the created shadow. This is the default.

  • Shadow only will output only the created shadow.

  • Shadow minus image will output the created shadow but subtracts the area hidden by the image.
