605% RaiseImage() creates a simulated three-dimensional button-like effect
606% by lightening and darkening the edges of the image. Members width and
607% height of raise_info define the width of the vertical and horizontal
608% edge of the effect.
609%
610% The format of the RaiseImage method is:
611%
612% MagickBooleanType RaiseImage(const Image *image,
613% const RectangleInfo *raise_info,const MagickBooleanType raise,
614% ExceptionInfo *exception)
615%
616% A description of each parameter follows:
617%
618% o image: the image.
619%
620% o raise_info: Define the width and height of the raise area.
621%
622% o raise: A value other than zero creates a 3-D raise effect,
623% otherwise it has a lowered effect.
624%
625% o exception: return any errors or warnings in this structure.
