You should read the chapter (14, IIRC) in ISO 32000-1:2008 about Tagged PDF and Structured PDF. Alt (for images or any other element in PDF) is handled via structure.

Hi Is there a way to get the alt text of an image in a pdf file with iText? I think the alt text is anywhere in the image stream... because there is no a dictionary for the alt text in the file. Perhaps overwriting PdfContentStreamProcessor including a new "\Span" operator ?
