/*
  CLISimpleOperatorImage() is an Internal subrountine to apply one simple
  image operation to the current image pointed to by the CLI wand.

  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)
    * one image replace by a list of images (-separate and -crop only!)

  In each case the result replaces the single original image in the list, as
  well as 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.

%  CLINoImageOperator() Applies operations that may not actually need images
%  in an image list.
%
%  The classic operators of this type is "-read", which actually creates
%  images even when no images are present.  Or image stack operators, which
%  can be applied (push or pop) to an empty image list.
%
%  Note that these operators may involve other special 'option' prefix
%  characters other  than '-' or '+', namely parenthesis and braces.
%
%  The format of the CLINoImageOption method is:
%
%      void CLINoImageOption(MagickCLI *cli_wand,const char *option,
%           const char *arg1, const char *arg2)
%
%  A description of each parameter follows:
%
%    o cli_wand: the main CLI Wand to use. (sometimes not required)
%
%    o option: The special option (with any switch char) to process
%
%    o arg1 & arg2: Argument for option, if required
%                   Currently arg2 is not used.

%  CLIOption() Processes the given option using the given CLI Magick Wand.
%  The option arguments can be variable in number, though at this time no more
%  that two is actually used by any option (this may change). Excess options
%  are simply ignored.
%
%  If the cli_wand->command pointer is non-null, then it is assumed that the
%  option has already been search for up from the CommandOptions[] table in
%  "MagickCore/options.c" using  GetCommandOptionInfo().  If not set this
%  routine will do the lookup instead. The pointer is reset afterward.
%
%  This action allows the caller to lookup and pre-handle any 'special'
%  options, (such as implicit reads) before calling this general option
%  handler to deal with 'standard' command line options.
%
%  The format of the CLIOption method is:
%
%       void CLIOption(MagickCLI *cli_wand,const char *option, ...)
%
%  A description of each parameter follows:
%
%     o cli_wand: the main CLI Wand to use.
%
%     o option: The special option (with any switch char) to process
%
%     o args: any required arguments for an option (variable number)
%
%  Example Usage...
%
%    CLIoption(cli_wand,"-read","rose:");
%    CLIoption(cli_wand,"-virtual-pixel","transparent");
%    CLIoption(cli_wand,"-distort","SRT:","30");
%    CLIoption(cli_wand,"-write","rotated_rose.png");
