+%  SimpleOperationImage() apply one simple operation on one image.
+%  The image however may be part of a longer list of images.
+%
+%  The image in the list may be modified in three different ways...
+%
+%    * directly modified (EG: -negate, -gamma, -level, -annotate, -draw),
+%    * replaced by a new image (EG: -spread, -resize, -rotate, -morphology)
+%    * replace by a list of images (-separate and -crop only!)
+%
+%  In each case the result is returned into the list, and the pointer to the
+%  modified image (last image added if replaced by a list of images) is
+%  returned.  As the image pointed to may be replaced, the first image in the
+%  list may also change.  GetFirstImageInList() should be used by caller if
+%  they wish return the Image pointer to the first image in list.
+%
+%  The format of the SimpleOperationImage method is:
+%
+%    MagickBooleanType SimpleOperationImage(ImageInfo *image_info,
+%        const int argc,const char **argv,Image **image)
+%
+%  A description of each parameter follows:
+%
+%    o image_info: the image info..
+%
+%    o argc: Specifies a pointer to an integer describing the number of
+%      elements in the argument vector.
+%
+%    o argv: Specifies a pointer to a text array containing the command line
+%      arguments.
+%
+%    o image: the image.
+%
+%    o exception: return any errors or warnings in this structure.
