%  MogrifyImageCommand() transforms an image or a sequence of images. These
%  transforms include image scaling, image rotation, color reduction, and
%  others. The transmogrified image overwrites the original image.
%
%  The format of the MogrifyImageCommand method is:
%
%      unsigned int MogrifyImageCommand(ImageInfo *image_info,const int argc,
%        char **argv,char **metadata,ExceptionInfo *exception)
%
%  A description of each parameter follows:
%
%    o image_info: The image info.
%
%    o argc: The number of elements in the argument vector.
%
%    o argv: A text array containing the command line arguments.
%
%    o metadata: any metadata is returned here.
%
%    o exception: Return any errors or warnings in this structure.
