Remove or hide PDF layer using ABCPdf?

Question

Is is possible to remove or hide a layer from a PDF using ABCPdf or another framework?

Answer 1

The following C# example shows how layer 2 of page 1 can be deleted:

Doc theDoc = new Doc();
theDoc.Read("source.pdf");
int thePages = theDoc.GetInfoInt(theDoc.Root, "Pages");
int thePage = theDoc.GetInfoInt(thePages, "Page 1");
int theLayer = theDoc.GetInfoInt(thePage, "Content 2");
theDoc.Delete(theLayer);
