Can I use iText to add such named destinations on the fly?
The main concern is
1. can iText, or PDFBox or other tools capable of adding names
destinations?
2. what is the speed of iText's opening-modify-save the PDF? This is a
question analogous to the concept of "linearized PDF" which enables fast
viewing for web browsers by organizing page information to more "front" of the
document stream. If I would like to add named destinations to a PDF with iText,
can they be prepended before actually fully loading the entire document, using
C#/Java operations like simply appending something to the existing file at the
front, without even loading the entire one; or we must loading the entire
content first and then add the named destinations?

No, there is not.
If you have a PDF where you need this level of viewing control, preparing it in
advanced with named destinations is the best approach.
Or perhaps if you tell us what you end goal is we might be able to help.

No directly ways of doing that, like appending
http://...example.pdf#page=1&xCoord=200&yCoord=300 ?

Yes, if you prepare the PDF first, you can use named destinations.

Hello,
Thanks very much!
However, although there are
{
page number
specific comment
view
zoom level
}
parameters that can be embedded in URL, there is no option to exactly specify
the coordinate location associated with opening a specific page.
Can that actually be done?

Please take a look at the following document for more info:

You are looking for the "view" parameter. ------------------------------------------------------------------------------
