// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_LoadSaveConvert();
// Call the diagram constructor to load a VSD diagram
Diagram diagram = new Diagram(dataDir + "ExportToImage.vsd");
// Save Image file
diagram.Save(dataDir + "ExportToImage_out.png", SaveFileFormat.PNG);

It is also possible to save a particular page to image, instead of the entire document:

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_LoadSaveConvert();
// Load diagram
Diagram diagram = new Diagram(dataDir + "ExportPageToImage.vsd");
// Save diagram as PNG
ImageSaveOptions options = new ImageSaveOptions(SaveFileFormat.PNG);
// Save one page only, by page index
options.PageIndex = 0;
// Save resultant Image file
diagram.Save(dataDir + "ExportPageToImage_out.png", options);
