%  MogrifyImage() applies image processing options to an image as prescribed

%
%  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.

%
%  A description of each parameter follows:

%  MogrifyImages() applies image processing options to a sequence of images as
%  prescribed by command line options.
%
%  The format of the MogrifyImage method is:
%
%      MagickBooleanType MogrifyImages(ImageInfo *image_info,const int argc,
%        const char **argv,Image **images,Exceptioninfo *exception)
%
%  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 images: The images.
%
%    o exception: Return any errors or warnings in this structure.
