%  window can be specified by id or name or be selected by clicking the
%  mouse in the desired window.  The keyboard bell is rung once at the

%  ImportImageCommand() reads an image from any visible window on an X server
%  and outputs it as an image file. You can capture a single window, the
%  entire screen, or any rectangular portion of the screen.  You can use the
%  display utility for redisplay, printing, editing, formatting, archiving,
%  image processing, etc. of the captured image.</dd>
%
%  The target window can be specified by id, name, or may be selected by
%  clicking the mouse in the desired window. If you press a button and then
%  drag, a rectangle will form which expands and contracts as the mouse moves.
%  To save the portion of the screen defined by the rectangle, just release
%  the button. The keyboard bell is rung once at the beginning of the screen
%  capture and twice when it completes.
%
%  The format of the ImportImageCommand method is:
%
%      MagickBooleanType ImportImageCommand(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.
