Hi Asad,

Yes FYA

tenant_setup_tenant.pdf (34.5 KB)
tenant_setup_tenant_invalid.pdf (16.0 KB)

  • tenant_setup_tenant.pdf contains valid bookmarks/ hyperlinks ,named destination
  • tenant_setup_tenant_invalid.pdf contains invalid bookmarks/hyperlinks, named destination

Please check following code snippet in order to get named destinations from PDF document and share your feedback with us if you have other different requirements:

Get Named Destinations from PDF document

Document doc = new Document(dataDir + "tenant_setup_tenant.pdf");
DestinationCollection dest = doc.Destinations;
Dictionary<string, int> Result = new Dictionary<string, int>();
for (int index = 0; index < dest.Count; index++)
{
 KeyValuePair<string, object> asdf = (KeyValuePair<string, object>)dest[index];
 int aspage = dest.GetPageNumber(asdf.Key, true);
 Result.Add(asdf.Key, aspage);
}

Furthermore, you can also read particular named destination using following code:

Get Particular Named Destination

string destinationName = "dest1";
Document doc = new Document("src.pdf");
if (doc.NamedDestinations[destinationName] !=null)
  Console.WriteLine("Destination exists");
else
  Console.WriteLine("Destination doe not exist");

Hi Asad,
I tried the following code. I am getting java.lang.NoClassDefFoundError: com/aspose/pdf/nameddestinations/NamedDestinationCollection. I am using apose 19.2.pdf version

The above code snippet was in C#.NET. However, in case you are using it in Java, would you kindly share the complete code snippet and JDK version in which you are testing it.

Hi Asad,

here is the code I I had written in Java :
com.aspose.pdf.Document pdfDocument = null;
NamedDestinationCollection namedDestinations = pdfDocument.getNamedDestinations();
if(null != namedDestinations.get_Item(“some named destinaion”)) {
ExplicitDestination exp = (ExplicitDestination) namedDestinations.get_Item(named.getName());
pageNum = exp.getPageNumber();
if(pageNum == 0) {
List namedDestinBk = (List) objMap.get(BoConstants.PDF_NAMED_BK);
namedDestinBk.add(LocalizedTextHelper.getText(“ls-pub-validation-295”, new Object[] { childOutlineItem.getTitle() }).concat("\n"));
}
} else {
List namedDestinBk = (List) objMap.get(BoConstants.PDF_NAMED_BK);
namedDestinBk.add(LocalizedTextHelper.getText(“ls-pub-validation-295”, new Object[] { childOutlineItem.getTitle() }).concat("\n"));
}

I am using jdk1.8.0_171 veersion

Would you kindly try calling NamedDestinationCollection as follows:

com.aspose.pdf.nameddestinations.NamedDestinationCollection namedDestinations = pdfDocument.getNamedDestinations();

Also, try using Aspose.PDF for Java 19.12. In case you still face any issue, please feel free to let us know.
