Description :

An AREA element defines the shape and coordinates of a region within a client side image MAP.

Header Identifies the record as a CDAREAELEMENT
Flags Reserved for future use

This structure is followed by the description of the shape. If AREA_SHAPE_xxx equals AREA_SHAPE_RECT then we are dealing with a rectangle whose area is defined in CDRECT. If AREA_SHAPE_xxx equals AREA_SHAPE_CIRCLE then we are dealing with a circle whose area is defined in CDRECT. If AREA_SHAPE_xxx equals AREA_SHAPE_POLYGON then we are dealing with a polygon whose area is defined with CDBPOINT.
