Using Annotations in Document Workflows
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 via the mouse and
keyboard. PDF includes a wide variety of standard annotation types, described in detail in
the
PDF 1.6 Reference .
Many of the standard annotation types can be displayed in either the open or the closed
state. When closed, they appear on the page in some distinctive form depending on the
specific annotation type, such as an icon, a box, or a rubber stamp. When the user activates
the annotation by clicking it with the mouse, it exhibits its associated object, such as
opening a pop-up window displaying a text note or playing a sound or a movie.
You can access and manipulate annotation data from both a plug-in and Acrobat
JavaScript. However, you can only create new annotation types using a plug-in or the IAC
API; you cannot create new annotation types from JavaScript.
Annotations and JavaScript
You can set, modify and access annotation information using the Acrobat JavaScript
annot object. However, you cannot create a new annotation type from JavaScript. To do
this, you must use a plug-in or the IAC API.

●
Add note comments
●
Make text edits
●
Highlight, cross out, or underline text

Add or delete custom stamps (see “Using Stamps in Approval Workflows” on page 71 )

page 71 )
●
