     BinaryFileStream bstream = new BinaryFileStream(fileArray);

     //Set the image object to use BinaySgtream object

     img1.getImageInfo().setImageStream(bstream);



     //Save the PDF file

     pdf.save("d:/pdftest/Image2PDF.pdf");

        }

        // Create the byte array to hold the data

        byte[] bytes = new byte[(int)length];

        // Read in the bytes

        int offset = 0;

        int numRead = 0;

        while ( (offset < bytes.length)

                &&

                ( (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) ) {

            offset += numRead;

        }

        // Ensure all the bytes have been read in

        if (offset < bytes.length) {

            throw new IOException("Could not completely read file " + file.getName());

        }
