I'm trying to get a handler of text box instance and get its contents (text value).
I have read Acrobat PDF API reference and developer guide, but couldn't find about that...
Who's know a way to get each pointers of text boxes by using acrobat PDF API script?
(it means an address handler, not coordinate)
You can't. JS doesn't have access to that level of the PDF structure. The
only thing you can get close to is by using the getPageNthWordQuads, which
will return the location of a single word on the page.
