(r): Attribute or child element is required. (m): Child element can be used multiple times.

Description

Renders a polygon on the acetate layer using the OBJECT element or defines a polygon using the FIELDVALUE, FEATURE, or SPATIALFILTER elements.

Restrictions

When parent element is OBJECT in an acetate layer, one symbol element is required, and only one can be used at a time.
The polygon must be closed - the beginning and ending coordinate pairs must be identical.

Notes

For the different options of representing geometry in an acetate layer, see OBJECT.

Attribute	Usage
coords	X,y coordinates representing a line. Coordinate x,y values are separated by white space, and coordinate pairs are separated by a semicolon by default. The separators can be changed by using SEPARATORS.
