Initial value:

 (
  "Composites an RGBA nrrd over "
  "a background color (or image), after doing gamma correction, "
  "then quantizes to an 8-bit image.  Actually, the "
  "input nrrd can have more than 4 values per pixel, "
  "but only the first four are used.  If the RGBA nrrd "
  "is floating point, the values are taken at face value; "
  "if it is fixed point, the values interpreted as having "
  "been quantized (so that 8-bit RGBA images will act as "
  "you expect).  When compositing with a background image, the given "
  "background image does not have to be the same size as the input "
  "image; it will be resampled (with linear interpolation) to fit. ")
