Comments

This function is valid for the following annotation objects:

Curve

Closed Curve

Freehand

Freehand Hotspot

Polygon

Polyline

In addition, the Automation object stores node settings along with the other object default settings

Note:

The last node is always shown. Therefore, using a large value for uGapNodes will probably result in only the first and last nodes being shown.
