8.4 Annotations
An
annotation
associates an object such as a note, sound, or movie with a location
on a page of a PDF document, or provides a way to interact with the user by
means of the mouse and keyboard. PDF includes a wide variety of standard an-
notation types, described in detail in Section 8.4.5, “Annotation Types.”
Many of the standard annotation types may be displayed in either the
open
or the
closed
state. When closed, they appear on the page in some distinctive form, such
as an icon, a box, or a rubber stamp, depending on the specific annotation type.
When the user
activates
the annotation by clicking it, it exhibits its associated ob-
ject, such as by opening a pop-up window displaying a text note (Figure 8.2) or by
playing a sound or a movie.

We asked each candidate company to distribute to 225
randomly selected employees the Great Place to Work
Trust Index. This employee survey was designed by the
Great Place to Work Institute of San Francisco to evaluate
trust in management, pride in work/company, and
camaraderie. Responses were returned directly to us.
Each company was also required to fill out the Hewitt
People Practices Inventory, a comprehensive 29-page
questionnaire designed by our partner in this project,
Hewitt Associates of Lincolnshire, Ill., a leading
management consulting firm. Finally we asked each of our
candidates to send us additional corporate materials, such
