Examples of org.jpedal.io.PdfFileReader

org.jpedal.io.PdfFileReader
provides access to the file using Random access class to read bytes and strings from a pdf file. Pdf file is a mix of character and binary data streams

    /**
        * read the form data from the file
        */
       final public PdfFileInformation readPdfFileMetadata(PdfObject metadataObj,PdfObjectReader currentPdfFile) {


           PdfFileReader objectReader=currentPdfFile.getObjectReader();
           ObjectDecoder objectDecoder=new ObjectDecoder(currentPdfFile.getObjectReader());


           //read info object (may be defined and object set in different trailers so must be done at end)
           DecryptionFactory decryption=objectReader.getDecryptionObject();
           PdfObject infoObject=objectReader.getInfoObject();
           if(infoObject!=null &&(!(decryption!=null && (decryption.getBooleanValue(PDFflags.IS_FILE_ENCRYPTED) || decryption.getBooleanValue(PDFflags.IS_PASSWORD_SUPPLIED)))))
               readInformationObject(infoObject,objectDecoder);


           //read and set XML value
           if(metadataObj!=null){


               String objectRef=new String(metadataObj.getUnresolvedData());


               //byte[] stream= metadataObj.DecodedStream;


               //start old
               //get data
               MetadataObject oldMetaDataObj =new MetadataObject(objectRef);
               objectReader.readObject(oldMetaDataObj);
               byte[] oldstream= oldMetaDataObj.getDecodedStream();
               /** breaks on encrypted (ie preptool)
                boolean failed=PdfReader.checkStreamsIdentical(stream,oldstream);


                if(failed)
