Adobe acrobat 7.0.5 sdk User Manual

Accessibility

If a PDF document is untagged, you can convert it to a tagged PDF using Acrobat 
Professional. 

Acrobat Standard provides only minimal support tagging and no way to review or 
repair accessibility problems.

On the tagged PDF document, perform an accessibility Full Check to isolate problems with 
PDF accessibility.

To help improve the accessibility of tagged PDF documents, you can use the Acrobat user 
interface or the Acrobat SDK to:

●

Create document navigation by adding bookmarks to the document (see 

●

Add alt text to images

●

Create hyperlinks, which enhances accessibility because it is easier to activate a 
hyperlink than to search for a specific reference point in the same or another document 
(see 

)

●

Add watermarks that optimize the accessibility of the PDF document (see 

●

Manipulate the tag structure tree using the 

 APIs from a plug-in (see the 

Acrobat and PDF Library API Overview)

The follwoing accessibility tips can make your forms more easily usable by all users.

Every field that is not hidden should contain a user-friendly name. This name is spoken 
when a user acquires the focus to that field and should give an indication of the field’s 
purpose. For example, if a field is named 

, a good short description would be 

First Name. The name should not depend on the surrounding context. For instance, if a form 
asks for the first name of both a person and their spouse, the field in the spouse section 
might be named Spouse’s First Name. 

This description is also displayed as a tooltip when the user positions the mouse over the 
field.
