thanks in advance.

Answer 1

I really want to save a special text to a Image,just
like text "dobetter"-> dobetter.jpg ,
what can i do next?To save a java.awt.image.BufferedImage to a file: use javax.imageio.ImageIO.
To put text onto a BufferedImage: render onto its Graphics2D object:
Demo:
import java.awt.*;
import java.awt.font.*;
import java.awt.geom.*;
import java.awt.image.*;
import java.io.*;
import javax.imageio.*;
import javax.swing.*;
public class X {
    public static void main(String[] args) throws IOException {
        String text = "Hello World";
        Font font = new Font("Lucida Bright", Font.PLAIN, 64);
        FontRenderContext frc = new FontRenderContext(null, true, true);
        Rectangle2D bounds = font.getStringBounds(text, frc);
        int w = (int) Math.ceil(bounds.getWidth());
        int h = (int) Math.ceil(bounds.getHeight());
        BufferedImage image = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
        Graphics2D g = image.createGraphics();
        g.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
        g.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, RenderingHints.VALUE_FRACTIONALMETRICS_ON);
        Paint paint = new GradientPaint(0, 0, Color.GREEN, 10, 10, new Color(0, 128, 0), true);
        g.setPaint(paint);
        g.setFont(font);
        g.drawString(text, -(float)bounds.getX(), -(float)bounds.getY());
        g.dispose();
        ImageIO.write(image, "jpeg", new File("hello.jpeg"));
}
