ireport图片流转换PDF问题

1、ireport报表传输图片文件流转换为PDF文件时图片显示问题？

    //
    OutputStream outputStream = response.getOutputStream();
        response.setContentType("application/pdf");
        response.addHeader("Content-Disposition", "inline;fileName=file.pdf");
        response.setCharacterEncoding("UTF-8");
        JasperRunManager.runReportToPdfStream(inputStream, outputStream, map, new JREmptyDataSource());

图片显示不出来，将原有的内容覆盖
