% CompareImagesCommand() compares two images and returns the difference between

% them as a distortion metric and as a new image visually annotating their

% differences.

|
% The format of the CompareImagesCommand method is:

%
|
% MagickBooleanType CompareImagesCommand(ImageInfo *image_info,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.
