How to remove buttons from a PDF

[John Liston <li...@asconline.com>]

How do I use PDFBox to remove the "About" etc. buttons from the top edge of this PDF, so that I may then view it without them? 

https://www.dropbox.com/s/781cgwn4m2grose/PAMV1A.pdf?dl=0 

I tried PDDocument.getDocumentCatalog().getAcroForm().flatten() without success.  How can I get rid of the buttons?

Thanks,
John Liston

This removes the cmdAbout button only. You'd need to modify the code so 
that it deletes all that starts with "cmd".



public class RemoveAnnot
{
     public static void main(String[] args) throws IOException
     {
         PDDocument doc = PDDocument.load(new File("PAMV1A.pdf"));
         List<PDAnnotation> annotations = doc.getPage(0).getAnnotations();
         for (int i = 0; i < annotations.size(); ++i)
         {
         PDAnnotation ann = annotations.get(i);

             String s = ann.getCOSObject().getString(COSName.T);
             if ("cmdAbout".equals(s))
             {
                 annotations.remove(ann);
                 break;
             }
         }
         doc.save(new File("PAMV1A-new.pdf"));
         doc.close();
     }
}
