%
% A description of each parameter follows:

% o windows: Specifies a pointer to a XWindows structure.
%
% o image: Specifies a pointer to a Image structure; XMagickCommand
% may transform the image and return a new image pointer.
%
% o state: Specifies an unsigned int; XMagickCommand may return a
% modified state.
