Comments

The ANNPOINT structure is like a Windows POINT structure, except that it uses double-precision floating point values.

Coordinates of an object's points are relative to its container object. The coordinates are interpreted using the container's scaling factors and offsets, which are described in Low-Level Coordinate System for Annotations.
