About PDF Library and plug-in applications
The Acrobat core API and the PDF Library API enable you to create plug-ins and PDF Library applications to

The following diagram shows the relationship between the PDF Library API and the Acrobat core API.
For information about creating an Acrobat core API or project or PDF Library API, see
PDF Library Applications" on page
