Java 外部字体加载后输出图片字体无法识别到

Question

楼主做报表，用的ireport，需要用到条形码，由于条码下方的字体用到OCR-B 10 BT这个字体，
外部写一个条码工具集成到ireport.
barcode4j/zxing 下方的条码字体需要自己画上去
但是Font加载OCR-B 10 BT.ttf字体后，测试了下输出效果，结果图片的字体无法正常显示。

public static String create(String str, String filePath, int width, int height) throws Exception{

    String fileName = System.currentTimeMillis() + ".jpg";
    String path = filePath + "/" + fileName;
    File file = new File(path);
    BufferedImage bi = new BufferedImage(width, height,BufferedImage.TYPE_INT_RGB);
    Graphics2D g2 = (Graphics2D) bi.getGraphics();
    g2.setBackground(Color.WHITE);
    g2.clearRect(0, 0, width, height);
    String ttf = "C:/Users/Administrator/Desktop/OCR-B 10 BT/OCR-B 10 BT.ttf";
//        Font font = new Font("OCR-B 10 Pitch BT", Font.BOLD, 25);//OCR-B 10 Pitch BT
    Font font = Font.createFont(Font.TRUETYPE_FONT, new File(ttf));
    font = font.deriveFont(Font.BOLD, 12); // 粗体比Font.PLAIN清晰
//        FileInputStream aixing = new FileInputStream(new File("C:/Users/Administrator/Desktop/tt0646z_/tt0646z_.ttf"));
//        Font dynamicFont = Font.createFont(Font.TRUETYPE_FONT, aixing);
//        Font font = dynamicFont.deriveFont(25);
    g2.setFont(font);
    g2.setPaint(Color.RED);

    FontRenderContext context = g2.getFontRenderContext();
    Rectangle2D bounds = font.getStringBounds(str, context);
    double x = (width - bounds.getWidth()) / 2;
    double y = (height - bounds.getHeight()) / 2;
    double ascent = -bounds.getY();
    double baseY = y + ascent;

    g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,
            RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
    g2.drawString(str, (int) x, (int) baseY);
    try {
        ImageIO.write(bi, "png", file);
    } catch (IOException e) {
        e.printStackTrace();
    }finally {
//            fb.close();
//            fi.close();
    }
    return file.getPath();
}

估计是字体并没有加载成功，你的代码呢？
