Aspose.Diagram for .NET
Aspose.Diagram for .NET is a specialized API designed to work with Microsoft Visio files. It allows developers to create, manipulate & convert native Visio file formats from within ASP.NET web applications, web services, Windows applications and Mono. Developers can create diagrams from scratch as well as easily load existing files and manipulate the elements of the diagram to export the result in other Visio formats, images or fixed-layout formats.
This .NET Diagram API is an alternative to the Microsoft Visio Object Model and provides 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, compact and provides common functionality so that developers have to write less code when performing common tasks.

Simple, Fast & Reliable Conversion of Visio Files
Companies generate technical diagrams in Microsoft Visio and would like to be able to share this information. The problem, however, is that the common users would not be able to load such visuals unless they have installed Microsoft Visio or some other tool that could load Visio specific file formats. One of the ways of solving this problem is converting Visio diagrams to universal formats such as PDF, HTML & raster images, which do not require special programs to be installed on the machine.
Aspose.Diagram for .NET has its own conversion engine, which works independently of any other software, and can convert any supported Visio file format to any of the supported format with just a few lines of code. The conversion process is quick yet reliable, offering you the high fidelity results regardless of the resultant file format.
Save diagram in different formats - C#
// load file to be converted var diagram = new Aspose.Diagram.Diagram(dir + "template.vsdx"); // convert to other formats diagram.Save(dir + "output.pdf", Aspose.Diagram.SaveFileFormat.PDF); diagram.Save(dir + "output.html", Aspose.Diagram.SaveFileFormat.HTML); diagram.Save(dir + "output.jpg", Aspose.Diagram.SaveFileFormat.JPEG);
Manipulate Microsoft Visio Diagrams
Aspose.Diagram for .NET API allows to read Microsoft Visio files in native VSD/VSDX format as well as other Visio formats including VSS, VST, VSX, VTX, VDW, VDX, VSSX, VSTX, VSDM, VSSM and VSTM. The contents of the diagram can be manipulated through the Aspose.Diagram API. After making the required changes to the Visio file, the file can then be written to disk in any of the supported formats.
Access Data from Visio Diagrams
Aspose.Diagram for .NET allows developers to easily read the data of the Visio diagram like Document Properties, Pages, Masters, Shapes, Images, Connects, Solution XML, Comments, Hyperlinks, StyleSheet, Layers, User-defined cells and so on.
Print Diagrams with Ease
Aspose.Diagram for .NET allows to print diagrams using different options, with just a few lines of code. You can choose to print with default settings, print to a specific printer or choose to print a range of pages.
Print diagrams on physical printer - C#
// load file to be printed var diagram = new Aspose.Diagram.Diagram(dir + "template.vsdx"); // print to default printer diagram.Print(); // print while specifying printer name & print job diagram.Print("LaserJet1100", "Job Name");
Microsoft Office Automation – Not Needed
Aspose.Diagram for .NET is built using managed code that never needs Microsoft Office or Microsoft Visio to be installed on the machine to work with Visio files processing. It is a perfect Microsoft Office Visio automation alternative in terms of supported features, security, stability, scalability, speed and price.
