PASS
Use case(s): Fundamental 2: Text
Last updated on January 3, 2025
Description
The objective of this technique is to show how to tag non-text content that is intended to be consumed as text. In this example, graphics were used to place the word "paragraph" on the page, instead of text objects. To make the characters of this graphic extractable, ActualText on a separate Span tag is used. The ActualText matches the visual appearance of the related graphics.
Note: The Span tag is always the recommended choice if ActualText is required because ActualText removes the semantics of tags. In spite of the previous statement, ActualText may also work when the tag is one of the following: Lbl (outside of List structures), P, BibEntry, BlockQuote, Caption, Code, Note, Quote. However, ActualText should never be assigned to other tags.
Note: This passes PDF/UA requirements but not WCAG 1.4.5. Images of text are not allowed in WCAG.
