PdfProcessing

Generate, import and export PDF documents using C# and VB.NET with PdfProcessing for WPF. The library supports .NET Framework, .NET Core and .NET Standard. Its API offers two editing approaches—using native PDF elements, which allows you great control over the content structure, or editing the PDF document as a flow document, which enables you to autoflow content into pages.

Annotations associate an object with a location on a page of the PDF document, which provides the user with a way to interact. The Telerik WPF PdfProcessing library supports two types of annotations—link annotations and widget annotations. Link annotations represent a link to a destination elsewhere in the document or a URL action to be performed. Widget annotations on the other hand are used to define the visual appearance of and manage user interactions within the interactive form fields of the PDF document.

Destinations may be associated with outline items, annotations or actions. In each case, the destination specifies the view that the document automatically displays when the outline is open or the action is performed. Destinations can be represented as named destinations, which is particularly handy when you need to use a destination more than once.
