Make Accessible Plug-In

The MakeAccessible Plug-in creates a tagged Adobe PDF file from an untagged PDF file.

Characteristics of a tagged PDF:
- Page content is contained in a logical read order
- Word boundaries explicitly identified
- Font encodings mapped to standard font encoding
- Includes a structure tree comprised of a standard set of tags

Benefits of a tagged PDF:
- Can be read by a screen reader for greater accessibility
- Document reflow
- Can be saved as Rich Text Format (RTF).

Additional documentation:
Refer to http://access.adobe.com for additional information about creating accessible Adobe PDF documents.

Limitations/Known Issues

- Font Encodings: The MakeAccessible Plug-In maps fonts used in the document to a Unicode value. In some cases, a font encoding used within a PDF document does not contain enough information for the MakeAccessible Plug-In to map to a Unicode equivalent.

- Table Recognition: The MakeAccessible Plug-In supports simple table recognition. A simple table would be a table that includes a single line rule around each cell of the table. Tables that do not include complete rules may not be recognized as table content.

- Complex Graphic Recognition: Documents that contain complex graphics (especially vector based graphics) could take a long time to process.

- Complex Regions: Documents such as magazines, marketing collateral, and newspapers contain complex layout. In some instances, the MakeAccessible Plug-In will not be able to ascertain the appropriate logical read order of a complex layout.

- Layer Order: Layers of objects within a complex PDF may be rearranged in a different stacking order, resulting in a tagged Adobe PDF that does not look identical to the original PDF.
