try (Parser parser = new Parser(Constants.SamplePdf)) {
    // Get the document info
    IDocumentInfo documentInfo = parser.getDocumentInfo();
    // Iterate over pages
    for (int p = 0; p < documentInfo.getPageCount(); p++) {
        // Print a page number
        System.out.println(String.format("Page %d/%d", p + 1, documentInfo.getPageCount()));
        // Extract a text into the reader
        try (TextReader reader = parser.getText(p)) {
            // Print a text from the document page
            System.out.println(reader.readToEnd());
        }
