The Redaction annotation object (ANNOBJECT_REDACT) is a rectangle with default properties that are appropriate for blacking out an area. With the automated functions, the user clicks and drags to specify the rectangle in the current window.
The class for Redaction Annotation objects is LAnnRedact.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
With low-level functions, you must specify the defining rectangle. Other applicable properties have the following defaults, which you can change:
