pointsidentifies a two dimensional area within the bounding box specified by the other attributes by means of a series of pairs of numbers, each of which gives the x,y coordinates of a point on a line enclosing the area.

rotateindicates the amount by which this zone has been rotated clockwise, with respect to the normal orientation of the parent surface element as implied by the dimensions given in the msDesc element or by the coordinates of the surface itself. The orientation is expressed in arc degrees.

This example defines a non-rectangular zone: see the illustration in section 11.4 Advanced uses of Surface and Zone.

This example defines a zone which has been defined as larger than its parent surface in order to match the dimensions of the graphic it contains.

Note
The position of every zone for a given surface is always defined by reference to the coordinate system defined for that surface.
A graphic element contained by a zone represents the whole of the zone.
A zone may be of any shape. The attribute points may be used to define a polygonal zone, using the coordinate system defined by its parent surface.
