成绩描写

我想用Java编辑突变文原

以下:-https://i.stack.imgur.com/0qAKt.png

但是我没有晓得该怎样做。

请助助我!

推举谜底

叨教须要应用Graphics二D画制,并依据LinearGradientPaint API

应用LinearGRadientPaint对于象树立其Paint属性

比方:

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics二D;
import java.awt.LinearGradientPaint;
import java.awt.Paint;
import java.awt.RenderingHints;
import javax.swing.*;

@SuppressWarnings("serial")
public class GradientText extends JPanel {
 private static final int PREF_W = 三六0;
 private static final int PREF_H = 二00;
 private static final Font FONT = new Font(Font.DIALOG, Font.BOLD, 四六);
 private static final String TEXT = "This is my text";
 private static final int COLOR_COUNT = 三0;
 private static final Color BG = Color.BLACK;
 private Paint myPaint;

 public GradientText() {
  setBackground(BG);
  setPreferredSize(new Dimension(PREF_W, PREF_H));
  float[] fractions = new float[COLOR_COUNT];
  Color[] colors = new Color[COLOR_COUNT];
  for (int i = 0; i < colors.length; i++) {
fractions[i] = ((float)i) / COLOR_COUNT;
float hue = fractions[i];
colors[i] = Color.getHSBColor(hue, 一f, 一f);
  }
  myPaint = new LinearGradientPaint(0, 0, PREF_W, 0, fractions, colors);
 }

 @Override
 protected void paintComponent(Graphics g) {
  super.paintComponent(g);
  Graphics二D g二 = (Graphics二D) g;
  g二.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
  g二.setPaint(myPaint);
  g二.setFont(FONT);
  g二.drawString(TEXT, 二0, 一00);
 }

 private static void createAndShowGui() {
  GradientText mainPanel = new GradientText();

  JFrame frame = new JFrame("GradientText");
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  frame.getContentPane().add(mainPanel);
  frame.pack();
  frame.setLocationRelativeTo(null);
  frame.setVisible(true);
 }

 public static void main(String[] args) {
  SwingUtilities.invokeLater(() -> createAndShowGui());
 }
}

在此代码中,应用分红三0身材部门的色相/鼓以及度/明度色彩树立线性画绘对于象
