Aspose.Diagram for .NET

 
 

Aspose.Diagram for .NET is a specialized API designed to work with Microsoft Visio documents. It allows developers to create, manipulate & convert native Visio formats. 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 formats.

Aspose.Diagram for .NET supports almost all native Visio formats as well as some commonly used image & fixed-layout formats. This 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 documents on a server.

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 diagrams to universal formats such as PDF, HTML & raster images, which do not require special programs to be installed on the machine.

.NET Visio library has its own conversion engine, which works independently of any other software, and can convert any supported Visio format to any of the supported one with just a few lines of code. The conversion process is quick yet reliable, offering you the high fidelity results regardless of the resultant format.

Save the diagram in different formats - C#

// load file to be converted
var dgr = new Aspose.Diagram.Diagram(dir + "template.vsdx");
// convert to other formats
dgr.Save(dir + "output.pdf", Aspose.Diagram.SaveFileFormat.PDF);
dgr.Save(dir + "output.html", Aspose.Diagram.SaveFileFormat.HTML);
dgr.Save(dir + "output.jpg", Aspose.Diagram.SaveFileFormat.JPEG);

Manipulate Microsoft Visio Diagrams

Aspose.Diagram for .NET API allows reading Microsoft Visio files in native VSD/VSDX format as well as other formats including VSS, VST, VSX, VTX, VDW, VDX, VSSX, VSTX, VSDM, VSSM, and VSTM. The contents of the diagram can be manipulated through the API. After making the required changes to the document, the document 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 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 printing 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 the physical printer - C#

// load file to be printed
var dgrm = new Aspose.Diagram.Diagram(dir + "template.vsdx");
// print to default printer
dgrm.Print();
// print while specifying printer name & print job
dgrm.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 documents processing. It is a perfect Microsoft Office Visio automation alternative in terms of supported features, security, stability, scalability, speed and price.
