The little yellow speech balloon thing is something Acrobat/Reader draws for
specific kinds of annotations, I certainly don't have a list. It's not part of
the annotations' appearance streams. The paperclip icon is a direct result of
setting the PdfAnnotation's "Name" key to "Paperclip".
I don't think you can avoid the yellow balloon thingy, but the paperclip is
optional.
The ".put( PdfName.NAME, ... )" call is a call from PdfAnnotation's direct
superclass, "PdfDictionary".
A dictionary is just a bunch of key/value pairs.
Keys are always PdfNames, and PdfName has a huge list of predefined constants
for the vast majority of the dictionary keys you might need. This constant
happens to be named "NAME", which might be a tad confusing.
The values can be anything descended from PdfObject. In this case it's a
PdfString, with the value "Paperclip".
According to the PDF Reference, there are four "named" appearances that
Conformant Viewers must support, "Graph", "PushPin", "Paperclip", and "Tag".
PushPin is the default if no name is specified. And you can make up your own
so long as you provide an appearance stream (or are willing to put up with the
question mark Acrobat/Reader comes up with when it doesn't know how to draw an
annotation).
Any time iText doesn't support some feature in a more direct fashion, folks
like myself pull out our copies of the PDF reference and start making
lower-level PdfDictionary (and PdfArray, PdfString, and so forth) calls. iText
can do just about anything the PDF reference defines, but the higher level
support is often missing from the nooks and crannies, such as this one.
OTOH, now that you know, it's easy to call "myAnnot.put(PdfName.NAME, new
PdfString("Graph");" or whatever it is that you want. Acrobat/Reader will whip
up the annotation appearance for you. They're not a part of
"movie_annotations_3.pdf", they were generated when the file was opened.
