右对齐图像上的文本

[英]Right align text on image

   Graphics g = image.getGraphics(); 
     FontMetrics fm = g.getFontMetrics();
      int actual_width= fm.stringWidth("My Value");
     drawString("My Value",total_width-actual_width,ypos);
    g.dispose();
    ImageIO.write(image, "bmp", new File(c:\\output.bmp));
