如何使用Java将图像剪切成文本形状？

class PictureText {

    public static void main(String[] args) throws Exception {
        URL imageUrl = new URL("https://i.sstatic.net/Nqf3H.jpg");
        BufferedImage originalImage = ImageIO.read(imageUrl);
        BufferedImage textImage = new BufferedImage(
            originalImage.getWidth(),
            originalImage.getHeight(),
            BufferedImage.TYPE_INT_ARGB);
        Graphics2D g = textImage.createGraphics();
        FontRenderContext frc = g.getFontRenderContext();
        Font font = new Font(Font.SANS_SERIF, Font.BOLD, 250);
        GlyphVector gv = font.createGlyphVector(frc, "Cat");
        Rectangle2D box = gv.getVisualBounds();
        int xOffset = 25 + (int)-box.getX();
        int yOffset = 80 + (int)-box.getY();
        Shape shape = gv.getOutline(xOffset, yOffset);
        g.setClip(shape);
        g.drawImage(originalImage, 0, 0, null);
        g.setClip(null);
        g.setStroke(new BasicStroke(2f));
        g.setColor(Color.BLACK);
        g.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
        g.draw(shape);

        g.dispose();

        File outputFile = new File("cat-text.png");
        ImageIO.write(textImage, "png", outputFile);
        Desktop.getDesktop().open(outputFile);
    }
}
