java - 如何使用 Java 从数据库打印 Itext Pdf 报告上的印地语文本？

Question

我在我的 JavaFX 项目中使用 itext 库生成 pdf。现在我想从报告内的数据库打印印地语、旁遮普语文本，我该怎么做。但是 IText 库无法识别印地语和旁遮普语 unicode ？？？ 这是我的代码

            out = new ByteArrayOutputStream();
    try {
        // initialize document with page size and margins
        document = new Document(PageSize.A4, 60, 40, 60, 60);
        this.setAlignmentOfCompanyInfo(Common.comp
                .getReportsHeaderAlignment());
        writer = PdfWriter.getInstance(document, out);

        writer.setPageEvent(new PageEventForAddressBookReport());
        document.open();PdfContentByte cb = writer.getDirectContent();
            PdfTemplate tp = cb.createTemplate(w, h);
            @SuppressWarnings("deprecation")
            Graphics2D g2 = tp.createGraphicsShapes(w, h);        
            g2.drawString("वर्तमान शेष", 200, 100);                
            g2.dispose();
            g2.setColor(Color.GREEN);
            cb.addTemplate(tp, 50, 400);
           BufferedImage bi = new BufferedImage(100, 20, BufferedImage.TYPE_INT_ARGB);
           Graphics2D ig2 = bi.createGraphics();
           ImageIO.write(bi, "PNG", new File("ourImageName.PNG"));
           Image image = Image.getInstance(tp);
           document.add(new Chunk(image,5,5));
document.close();

由于itext不支持白话，请将文本转换为位图并设置为图像。使用以下方法进行转换:

public Bitmap textAsBitmap(String text, float textSize, float stroke,
        int color) {

    TextPaint paint = new TextPaint();
    paint.setTextSize(textSize);

    paint.setAntiAlias(true);
    // paint.setTextAlign(Paint.Align.LEFT);

    paint.setAntiAlias(true);
    paint.setColor(color);
    // paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeJoin(Paint.Join.ROUND);
    paint.setStrokeWidth(20f);

    paint.setTypeface(Typeface.create(Typeface.DEFAULT, Typeface.BOLD));
    float baseline = (int) (-paint.ascent() + 3f); // ascent() is negative

    StaticLayout staticLayout = new StaticLayout(text, 0, text.length(),
            paint, 435, android.text.Layout.Alignment.ALIGN_NORMAL, 1.0f,
            1.0f, false);

    // int linecount = staticLayout.getLineCount();
    //
    // int height = (int) (baseline + paint.descent() + 3) * linecount + 10;

    Bitmap image = Bitmap.createBitmap(staticLayout.getWidth(),
            staticLayout.getHeight(), Bitmap.Config.ARGB_8888);

    Canvas canvas = new Canvas(image);
    // canvas.drawARGB(100, 100, 100, 100);

    staticLayout.draw(canvas);

    return image;

}
