%
%  RaiseImage() creates a simulated three-dimensional button-like effect
%  by lightening and darkening the edges of the image.  Members width and
%  height of raise_info define the width of the vertical and horizontal
%  edge of the effect.
%
%  The format of the RaiseImage method is:
%
%      MagickBooleanType RaiseImage(const Image *image,
%        const RectangleInfo *raise_info,const MagickBooleanType raise)
%
%  A description of each parameter follows:
%
%    o image: The image.
%
%    o raise_info: Define the width and height of the raise area.
%
%    o raise: A value other than zero creates a 3-D raise effect,
%      otherwise it has a lowered effect.
