Accessibility Overview (Angular)

This sample shows how to create a tagged PDF using the Expense Analysis Report sample as a base.

The sample uses the info.title, tagged, displayTitle and lang properties to satisfy the basic Tagged PDF requirements when creating the instance of the PdfDocument class.

The sample uses the tag method to create tags and mark content and the addTag method to add tags to the logical document tree. The artifact method is used to mark decorative content as artifacts.

Note: Tagged PDF requires document version 1.4 or higher.

This example uses Angular.
