ISO 32000-1:2008 a.k.a. PDF 1.7, clause 14.9 Accessibility Support covers
14.9.3 Alternate Descriptions, 14.9.4 Replacement Text, and 14.9.5 Expansion of
Abbreviations and Acronyms.
It has to do with Tagged PDF.
OK, so it is not an image feature, it is something optional Thanks for the
explanation, Peter.
To answer the origin question, PDFBox doesn't support the creation of Tagged
PDFs. This doesn't prevent anybody from creating the needed structures on their
own. But this is a lot of work and includes studying the PDF spec and some
sample PDFs

Dear users,
Can anyone give a hint on how to add a "alt text" to an image in a
pdf-document created by PDFBox.
I would like the text to appear when hovering over the image.
I have already added the image to the document and all is looking
good. Just missing the "alt text"
Never heard about something like an alt text. Where did you get that
from? Do you have an example?
Andreas
I'm using the code
PDImageXObject pdImage = PDImageXObject.createFromByteArray(doc,
imageBytes, "af_logo.png");
To add the image.
Thanks for your help
