Tilman,
The code I tried is:
byte[] bytes = // content of file as a byte array
PDDocument pdDocument = PDDocument.load( bytes );
PDDocumentCatalog cat2 = pdDocument.getDocumentCatalog();
PDPageLabels pageLabels = cat2.getPageLabels();
if ( pageLabels == null ) {
System.out.println( "Page labels missing " );
}
I'm getting "Page labels missing" on each document.
I have no idea of, or control over the process used to convert a Word file
into a PDF. I just inherited a bunch of PDFs that I'm trying to interpret.
