Add PDF Bookmarks

This article provides information on how to insert PDF bookmarks when converting a spreadsheet to PDF.

Aspose.Diagram allows you to add bookmarks on the fly. PDF bookmarks can drastically improve the navigability of long documents. When adding bookmark links to a PDF document, you can have precise control over the exact view you want, and you’re not limited to linking to a page. You can set up the precise view by positioning the target page, and then create the bookmark.

Please see the following sample code to find out how to add PDF bookmarks. The code read diagram, specifies PDF bookmarks with destination locations and generates the PDF file.

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_Intro();

// call the diagram constructor to load diagram from a VSD file
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");

PdfSaveOptions options = new PdfSaveOptions();
// Create a main PDF Bookmark entry object
PdfBookmarkEntry pbeRoot = new PdfBookmarkEntry();
// Specify its text
pbeRoot.setText("1.vsdx");
// Set the destination page
pbeRoot.setDestination(diagram.getPages().get(0));
pbeRoot.setOpen(true);
// Set its sub entry array list
pbeRoot.setSubEntry(new ArrayList());
// Create a sub PDF Bookmark entry object
PdfBookmarkEntry subPbe2 = new PdfBookmarkEntry();
// Specify its text
subPbe2.setText("Page 1");
// Set its destination
subPbe2.setDestination(diagram.getPages().get(1));
// Add the object to the main PDF root object
pbeRoot.getSubEntry().add(subPbe2);
// Set the PDF Bookmark root object
options.setBookmark(pbeRoot);
diagram.save(dataDir + "out.pdf", options);
