%  GetGeometry() parses a geometry specification and returns the width,
%  height, x, and y values.  It also returns flags that indicates which
%  of the four values (width, height, x, y) were located in the string, and
%  whether the x or y values are negative.  In addition, there are flags to
%  report any meta characters (%, !, <, or >).
%
%  The format of the GetGeometry method is:
%
%      MagickStatusType GetGeometry(const char *geometry,ssize_t *x,ssize_t *y,
%        size_t *width,size_t *height)
%
%  A description of each parameter follows:
%
%    o geometry:  The geometry.
%
%    o x,y:  The x and y offset as determined by the geometry specification.
%
%    o width,height:  The width and height as determined by the geometry
%      specification.
