%  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:
%
%      MagickBooleanType MogrifyImageCommand(ImageInfo *image_info,int argc,
%        const 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.

%  MogrifyImages() applies image processing options to a sequence of images as

%
%  The format of the MogrifyImage method is:

%        const MagickBooleanType post,const int argc,const char **argv,
%        Image **images,Exceptioninfo *exception)
%
%  A description of each parameter follows:
%
%    o image_info: the image info..
%
%    o post: If true, post process image list operators otherwise pre-process.
%
%    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 images: the images.
%
%    o exception: return any errors or warnings in this structure.
