Exporting to Image File Programming Sample

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(ExportToImage.class);

// Call the diagram constructor to load diagram from a VSD file
Diagram diagram = new Diagram(dataDir + "ExportToImage.vsd");

// Save as PNG
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-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(ExportPageToImage.class);     
// 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.setPageIndex(0);

//Save resultant Image file
diagram.save(dataDir + "ExportPageToImage_Out.png", options);
