ALT Text in PDFS for TIFF Images / Searchable Text in PDFs

Aspose.PDF Product Family
1

We are scanning black and white documents into TIFF files where each TIFF file represents a single page. We then OCR each page to extract the text.

Afterwards, we combine the TIFFS into a single PDF. We would like know if it is possible to add the extracted text back into the PDF to a) make it accessible to people who may be visually impaired and may not be able to view the image, and b) to make the PDF searchable. While we want the text to be associated with the document, we don't want for it to be visible. Is there a way to accomplish our objectives?

Thank you!

Dear Anthony,

Thank you for considering Aspose.

I think you can add the text with floating box [(http://www.aspose.com/Products/Aspose.Pdf/Api/Lets-start-with-Hello.html ](http://www.aspose.com/Products/Aspose.Pdf/Api/Lets-start-with-Hello.html)) and place the floating box outside the page.
