Browse classes, enumerations, and interfaces organized by functional area. ## Instantiating the Library The Library object must be instantiated on each thread before any of the PDFL objects are used. If the Library object is instantiated on any thread, it must also at least be instantiated on the main thread. In addition, for cleanup purposes, the Dispose method **must** be called on the Library object before the thread is terminated. A simple way to accomplish this is a **using** statement: ```csharp using (Library lib = new Library()) // your application code that uses PDFL goes here... ``` The Library object can be instantiated without specifying flags or a list of Resource locations. User resources will be placed first in the search list. ## Activating a License-Managed version To use an activation key, the *LibraryKey* member of the *Library* class can be set to a valid activation key **prior** to instantiating the library. ```csharp Library.LicenseKey = "xxxx-xxxx-xxxx-xxxx"; Library lib = new Library(); ``` ## Classes (150) -
