Working with figures and alternate text
Figures and other graphic data can be inaccessible to a user employing screen
reading technology to access a PDF document unless descriptive text, also known
as alternate text, is provided. Alternate text can be applied to figure elements
(similar to the HTML Alt tag used with a Figure/Image element).
To provide alternate text for figures:
Select the figure element in the Logical Structure Tree.
1
Choose Edit > Properties, or right click and select Properties from the context
2
menu.
Enter descriptive text in the Alternate Text text box.
3
Click OK.

Note: If alternate text has not been provided for a figure, the Make Accessible plug-
in may take any isolated text in the proximity of the figure and assign it as alternate
text for the figure. If the text has not been otherwise left in the structure, it is best to
create a new element for the text, and add appropriate alternate text for the figure as
described above.
