Windows Presentation Foundation (WPF) is a popular framework for making .NET applications. In addition to built-in controls, WPF supports the use of other control libraries to access new functionality, such as viewing and modifying several document formats with GdPicture.NET. With this single control, an application can view and edit images, PDFs, and other document types including Word and Excel documents.

GdPicture.NET works with .NET Core 3.0 and later. Over 100 different file formats are supported including PNG, SVG, Photoshop, PDF, Word documents, and many more. GdPicture.NET includes support for images with color depths from 1-bit to 128-bit and several color formats. A list of the supported document types is listed at

To demonstrate how easy the control is to use I will create a document viewer application using the control.
