60% CompareImageCommand() compares two images and returns the difference between
61% them as a distortion metric and as a new image visually annotating their
62% differences.
63%
64% The format of the CompareImageCommand method is:
65%
66% MagickBooleanType CompareImageCommand(ImageInfo *image_info,int argc,
67% char **argv,char **metadata,ExceptionInfo *exception)
68%
69% A description of each parameter follows:
70%
71% o image_info: the image info.
72%
73% o argc: the number of elements in the argument vector.
74%
75% o argv: A text array containing the command line arguments.
76%
77% o metadata: any metadata is returned here.
78%
79% o exception: return any errors or warnings in this structure.
