java swing graphics2d 拉绳不工作

Question

BufferedImage image=new BufferedImage(32,32,BufferedImage.TYPE_INT_ARGB);
        Graphics2D g2=image.createGraphics();
        g2.setBackground(Color.white);
        g2.setColor(Color.BLACK);
        g2.drawString("A",0,0);
        ImageIO.write(image,"PNG",new File("1.png"));

It just giving me an empty white image. Why?

Answer 1

Try:

    g2.drawString("A", 0, 16);

(0,0) is the upper left corner and the drawString coordinates are for the lower left point where you want to draw
