KEY         TYPE                    VALUE

Subtype     name                    (Required) The type of annotation that this dictionary describes; must be

Name        name                    (Optional) The name of an icon to be used in displaying the annotation.
                                    Viewer applications should provide predefined icon appearances for at least
                                    the following standard names:
                                         Graph                                 PushPin

                                    Note: The annotation dictionary’s AP entry, if present, takes precedence over the
                                    Name entry; see Table 8.15 on page 606 and Section 8.4.4, “Appearance
                                    Streams.”


          Sound Annotations

          A sound annotation (PDF 1.2) is analogous to a text annotation except that in-
          stead of a text note, it contains sound recorded from the computer’s microphone
          or imported from a file. When the annotation is activated, the sound is played.
          The annotation behaves like a text annotation in most ways, with a different icon
          (by default, a speaker) to indicate that it represents a sound. Table 8.36 shows the
          annotation dictionary entries specific to this type of annotation. Sound objects
          are discussed in Section 9.2, “Sounds.”

                       TABLE 8.36 Additional entries specific to a sound annotation
KEY           TYPE               VALUE

Subtype       name               (Required) The type of annotation that this dictionary describes; must be Sound
                                 for a sound annotation.

Sound         stream             (Required) A sound object defining the sound to be played when the annotation
                                 is activated (see Section 9.2, “Sounds”).
