+%
+%  PolynomialImage() returns a new image where each pixel is the sum of the
+%  pixels in the image sequence after applying its corresponding terms
+%  (coefficients and degree pairs) and a constant.
+%
+%  The format of the PolynomialImage method is:
+%
+%      Image *PolynomialImage(const Image *image,const size_t number_terms,
+%        const double *terms,ExceptionInfo *exception)
+%
+%  A description of each parameter follows:
+%
+%    o image: the image.
+%
+%    o number_terms: the number of terms in the list.  The actual list length
+%      is 2 x number_terms + 1 (the constant).
+%
+%    o terms: the list of polynomial coefficients and degree pairs and a
+%      constant.
+%
+%    o exception: return any errors or warnings in this structure.
