 com.aspose.pdf.License licensePdf = new com.aspose.pdf.License();

licensePdf.setLicense("Aspose.Total.Java.lic");

// bind the pdf document

com.aspose.pdf.facades.PdfExtractor pdfExtractor = new com.aspose.pdf.facades.PdfExtractor();

pdfExtractor.bindPdf("CodBar_DOC_2016_06_02_13_00_50_617.pdf");

// set page range for image extraction

pdfExtractor.setStartPage(1);

pdfExtractor.setEndPage(4);

// extract the images

System.out.println("Extracting images.....");

pdfExtractor.extractImage();

// save images to stream in a loop

while (pdfExtractor.hasNextImage())

{

   System.out.println("Getting next image....");

   // save image to stream

   ByteArrayOutputStream outputStreamImageStream = new ByteArrayOutputStream();

   pdfExtractor.getNextImage(outputStreamImageStream);

   InputStream imageStream = new ByteArrayInputStream(outputStreamImageStream.toByteArray());

   System.out.println("Recognizing barcode....");

   // recognize the barcode from the image stream above

   BarCodeReader barcodeReader = new BarCodeReader(imageStream, DecodeType.ALL_SUPPORTED_TYPES);

    barcodeReader.setRecognitionMode(RecognitionMode.ManualHints | RecognitionMode.MaxQuality);

    barcodeReader.setManualHints(ManualHint.ComplexBackground | ManualHint.IncorrectBarcodes | ManualHint.MedianSmoothing);

    barcodeReader.setOrientationHints(RecognitionHints.Orientation.Rotate180);

    while (barcodeReader.read())

    {

        System.out.println("Codetext found: " + barcodeReader.getCodeText() + ", Symbology: " + barcodeReader.getCodeType().toString());

    }

    // close the reader

    barcodeReader.close();

}
