When I try to extract an "encrypted" (which can be read in AcrobatReader)
document with:
pdfDocument = PDDocument.load( is );
PDFTextStripper pdfStripper = new PDFTextStripper();
parsedText = pdfStripper.getText( pdfDocument );
I get an empty string, and " o.apache.pdfbox.pdfparser.PDFParser - Document is
encrypted" is logged.
When, on the other hand, I do:
ContentHandler handler = new BodyContentHandler( -1 );
ParseContext context = new ParseContext();
parser = new AutoDetectParser();
context.set( Parser.class, parser );
parser.parse( is, handler, metadata, context );
parsedText = handler.toString();
I get to see the text/content of the very pdf.
1) What ist he preferred way to extract text from a
pdf("-that-can-be-read-in-AcrobatReader")?
2) Does the second approach possibly return "more than text"? Blobs? Binary
data?
