%  AnimateImageCommand() displays a sequence of images on any workstation
%  display running an X server. Animate first determines the hardware
%  capabilities of the workstation. If the number of unique colors in an image
%  is less than or equal to the number the workstation can support, the image
%  is displayed in an X window. Otherwise the number of colors in the image is
%  first reduced to match the color resolution of the workstation before it is
%  displayed.
%
%  This means that a continuous-tone 24 bits/pixel image can display on a 8
%  bit pseudo-color device or monochrome device. In most instances the reduced
%  color image closely resembles the original. Alternatively, a monochrome or
%  pseudo-color image sequence can display on a continuous-tone 24 bits/pixels
%  device.
%
%  The format of the AnimateImageCommand method is:
%
%      MagickBooleanType AnimateImageCommand(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.
