Attribute Value for Type Shape

A shape within an image, which can be "rect", "circle", "poly" or "default" (where "rect" denotes a rectangle and "poly" denotes a polygon)

The Shape Attribute Type is used in conjunction with the Coords Attribute Type in order to specify a region within an image map created using the Client-side Image Map Module. It is declared in the DTD as an Enumeration and can take one of the values:

rect

A rectangle

circle

A circle

poly

A polygon (with arbitrary positioning of its vertices)

default

"default" is the same as "rect" except that all parts of the image which are not already defined by a Shape/Coords pair also apply to this "default" Shape. Somewhat confusingly, the default value for the shape attribute (the shape which is assumed in the absence of this attribute) is "rect"
