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
to this type of annotation.
