“Redundant text links shall be provided for each active region of a server-side image map.“ – §1194.22(e)
“Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape.“ – §1194.22(f)
While image maps provide navigable links they often do so in an inaccessible fashion; that is, the links have no indicated target or role.
EXAMPLE: A document includes a map of the United States with each state including a hyperlink to more information.
RESOLUTION: Provide a list of the states with each state name as a link. These may be read or navigated using the keyboard.
While server-side image maps are theoretically possible in PDF, in practice they’re never seen. Nonetheless, this checkpoint detects them in the PDF and will require the user to verify that redundant text links are available.
Client-side image maps are specific to HTML and aren’t available in the PDF format.
What happens when I verify this Checkpoint?
The checkpoint is automatically assigned a status of not applicable if the page does not contain server-side image maps. If server-side image maps are detected, the user will be required to verify that redundant text links are available for each server-side image map link.
When to Pass or Fail this Checkpoint?
|Pass||Server side image maps have redundant text links on the page.|
|Fail||Server side image maps do not have redundant text links.|
|Not Applicable||No server side image maps are detected.|
|Remediation||Return to author to add redundant links.|
This checkpoint is automatic.
