%
%  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 value must form a proper geometry style specification of WxH+X+Y
%  of integers only, and values can not be separated by comma, colon, or
%  slash charcaters.  See ParseGeometry() below.
%
%  Offsets may be prefixed by multiple signs to make offset string
%  substitutions easier to handle from shell scripts.
%  For example: "-10-10", "-+10-+10", or "+-10+-10" will generate negtive
%  offsets, while "+10+10", "++10++10", or "--10--10" will generate positive
%  offsets.
%
%  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.

%  ParseGeometry() parses a geometry specification and returns the sigma,
%  rho, xi, and psi values.  It also returns flags that indicates which
%  of the four values (sigma, rho, xi, psi) were located in the string, and
%  whether the xi or pi values are negative.
%
%  In addition, it reports if there are any of meta characters (%, !, <, >, @,
%  and ^) flags present. It does not report the location of the percentage
%  relative to the values.
%
%  Values may also be separated by commas, colons, or slashes, and offsets.
%  Offsets may be prefixed by multiple signs to make offset string
%  substitutions easier to handle from shell scripts.
%  For example: "-10-10", "-+10-+10", or "+-10+-10" will generate negtive
%  offsets, while "+10+10", "++10++10", or "--10--10" will generate positive
%  offsets.
