Pdf layers

[dat.do]

Hello,

Is there a way to check if the existing pdf has layers? How to get information of that layers?
Note: I know there is a way to add layers but I don’t see any way to get layers from existing document. The code snippet below to get layers from existing pdf return null.

Document pdfDocument = new Document("sample.pdf");
pdfDocument.getPages().get_Item(1).getLayers(); // this is return NULL

Please find the test code, sample pdf - Generated by Aspose PDF - and test log in attachment

Layers shown in Foxit reader

Please also note that I have used latest version of 20.12

Thanks
