By default, when exporting to an accessible PDF, SmartArt graphics are included in the logical document structure as a figure. They receive a Figure structure element.
However, since SmartArt graphics are based on a list structure, in certain cases it may be more accessible to output them as a list rather than as a figure in the document structure.
Displaying the List Structure in PowerPoint
To view the list structure of a SmartArt graphic in PowerPoint:
- Select the SmartArt graphic.
- Click the small arrow on the left side of the SmartArt graphic. This opens the Text Pane showing the list structure.
When Should a SmartArt Graphic Be Exported as a List?
When exporting to an accessible PDF, you can choose whether the SmartArt graphic is output as a figure or as a list. Use the following criteria:
Figure
- The pure list structure does not fully convey the content and meaning of the SmartArt graphic.
- The visual representation is necessary to understand the content.
→ In this case, the SmartArt graphic should be exported as a figure.
Be sure to add alt text that describes the structure and content. For details, see the article Add Alt Text or Mark Object as Decorative.
List
- The list structure fully represents the content and meaning of the SmartArt graphic. (The SmartArt graphic in the previous section Displaying the List Structure in PowerPoint is a good example.)
- The visual representation is not required to understand the content.
→ In this case, you can export the SmartArt graphic as a list. Assistive technologies will then output the list structure, not the figure.
Advantages of exporting as a list:
- The structure is accurately represented and is often more accessible for users of assistive technologies, especially screen readers, than a long alt text.
- You save time because no complex alt text is needed.
How to Export SmartArt Graphics as a List
- Select the entire SmartArt graphic by clicking its outer frame.
- Open the axesSlide tab. Select the Role Mapping button to open the axesSlide - Role mappings and reading order task pane.
- Assign the role List to the SmartArt graphic. (You can find detailed instructions in the article Button "Role mapping".)
Done! The SmartArt graphic will now be output as a list in the logical document structure of the accessible PDF.
