用Java代码实现一幅春联详解

快过年了，闲来无事，那就用自己的专业发挥一下作用吧。接下来我们就用java代码写一幅春联呗。具体代码如下：

模板图片如下：

package com.zmh.daily.spring;

import javax.imageio.ImageIO;

import java.awt.*;

import java.awt.image.BufferedImage;

import java.io.File;

import java.io.IOException;

/**

public class Couplet {

//设置生成文件存放文件夹

final static String imageFolderPath = "/Users/sunshinezhang/Desktop/1/";

//设置背景图

final static String sourceFilePath = "/Users/sunshinezhang/Desktop/1/2.png";

//设置字体

final static String fontName = "宋体";

public static void main(String[] args) {

write();

}

public static void write() {

BufferedImage image = new BufferedImage(640 * 4, 640 + 2 * 640 * 7, BufferedImage.TYPE_INT_RGB);

Graphics g = image.createGraphics();

BHApqce g.drawImage(writeH("辞旧迎新"), 0, 0, 640 * 4, 640, null);

g.drawImage(writeV("旧岁又添几个喜"), 0, 640, 640 * 2, 2 * 640 * 7, null);

g.drawImage(writeV("新年更上一层楼"), 2 * 640, 640, 640 * 2, 2 * 640 * 7, null);

//输出文件

try {

ImageIO.write(image, "png", new File(imageFolderPath + "春联.png"));

} catch (IOException e) {

e.printStackTrace();

}

}

//横批

public static BufferedImage writeH(String text) {

char[] ch = text.toCharArray();

BufferedImage image = new BufferedImage(640 * ch.length, 640, BufferedImage.TYPE_INT_RGB);

Graphics g = image.createGraphics();

for (int i = 0; i < ch.length; i++) {

char c = ch[i];

g.drawImage(fontMark(String.valueOf(c)), 640 * i, 0, 640, 640, null);

}

g.dispose();

return image;

}

//上下联

public static BufferedImage writeV(String text) {

char[] ch = text.toCharArray();

BufferedImage image = new BufferedImage(2 * 640, 2 * 640 * ch.length, BufferedImage.TYPE_INT_RGB);

Graphics g = image.createGraphics();

for (int i = 0; i < ch.length; i++) {

char c = ch[i];

g.drawImage(fontMark(String.valueOf(c)), 0, 2 * 640 * i, 2 * 640, 2 * 640, null);

}

g.dispose();

return image;

}

public static BufferedImage fontMark(String content) {

try {

BufferedImage image = ImageIO.read(new File(sourceFilePath));

return fontMark(image, content);

} catch (IOException e) {

return null;

}

}

//文字标记

public static BufferedImage fontMark(BufferedImage bufImg, String content) {

Font font = new Font(fontName, Font.BOLD, 350);

Graphics2D graphics = bufImg.createGraphics();

graphics.setColor(Color.black);

graphics.setFont(font);

graphics.drawString(content, 230, 540);

graphics.dispose();

System.out.println(content);

return bufImg;

}

}

运行main方法以后，效果图如下：
