java – 带有背景图像的JTextArea的内部填充

这就是我的意思：

有没有什么方法可以添加一种向内缩进,以便文本不与图像的边缘重叠？

这是原始评论气泡图像.

这是代码：

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Graphics;
import java.awt.Image;

import javax.swing.GrayFilter;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;

public class myBackgroundSample {

    String file;

    public myBackgroundSample(String i) {
        file = i;
        setItUp();
    }

    public void setItUp() {
        final ImageIcon imageIcon = new ImageIcon(file);
        JTextArea textArea = new JTextArea() {
            Image image = imageIcon.getimage();

            public void paint(Graphics g) {
                setopaque(false);
                g.drawImage(image,this);
                super.paint(g);
            }
        };
        JFrame frame = new JFrame("Background Example");
        frame.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
        JScrollPane scrollPane = new JScrollPane(textArea);
        Container content = frame.getContentPane();
        content.add(scrollPane,BorderLayout.CENTER);
        frame.setSize(400,400);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        // Todo Auto-generated method stub
        String right = "chat1.jpg";
        myBackgroundSample temp = new myBackgroundSample(right);

    }
}
