SECTION 8.4 Anno ta tions
Additional state changes are made by adding text annotations in reply to the pre-
vious reply for a given user.
Text Annotations
A text annotation represents a “sticky note” attached to a point in the PDF docu-
ment. When closed, the annotation appears as an icon; when open, it displays a
pop-up window containing the text of the note in a font and size chosen by the
viewer application. Text annotations do not scale and rotate with the page; they
behave as if the NoZoom and NoRotate annotation flags (see Table 8.16 on page
608) were always set. Table 8.23 shows the annotation dictionary entries specific
to this type of annotation.
