Aspose.Diagram is a class library for working with Microsoft Visio files. It allows developers to work with VSD, VSDX, VSS, VST, VSX, VTX, VDW and VDX files on C#, VB.NET, ASP.NET web applications, web services, Mono and Windows applications. It allows you to open files and manipulate the elements of the diagram, from lines and fills, to more complex elements, and then export to VDX, VSX, VTX, XPS, HTML, SVG, SWF, XAML, image or PDF formats.
The class library is an alternative to the Microsoft Visio Object Model and provides a better performance. It makes use of the advanced functionality of Visio Services to manipulate Visio documents on a server. The API is extensible, easy to use and compact. It provides common functionality so that developers have to write less code when performing common tasks.
Aspose.Diagram is aimed at developers who need to work with Visio files from within their own applications. It allows developers to manipulate the file format quickly and easily, saving time and effort in developing a solution for working with Visio files.
