Re: Actual Text attribute

Actual Text should not be used for a page or pages of scanned text. The intent is that it is used for images of text...small pieces of text.

One issue is that adaptive technology has buffers and each adaptive technology has a different size buffer.

I've experienced PDF documents with so much content in an Alt or Actual Text attribute that the documents could not be opened while the AT was running and since AT must be running when an application/document is open, this renders the PDF inaccessible.

Theoretically, Actual Text is treated by the AT as if it were text and not an "alternate for text" or an image.

If you are working in InDesign, it is always better to work with text and not images of text. Using text let's you add the appropriate structure such as headings, lists and tables..which you can't do in either Alt or Actual Text.

Scanned images also create other accessibility problems if you have to reduce the size of the PDF...Whether it is text or images.
