用Java实现春联 支持自定义字体颜色
作者：洛阳泰山
大家好，本篇文章主要讲的是用Java编写春联 支持自定义字体颜色，感兴趣的同学赶快来看一看吧，对你有帮助的话记得收藏一下
最近看到一篇 Python代码写春联的文章，什么？！Python能搞，我Java这么牛逼的语言，必须得搞！以彰显我大java的威武，和无所不能！！！
首先找到一张春联背景图案（抱歉，图片素材不好找，那原作者的素材用用！！！）
接下就是见证奇迹的时刻，上代码
import sun.font.FontDesignMetrics;
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.*;
public class Couplet {
//设置生成文件存放文件夹
final static String imageFolderPath = "C:\\Users\\liuya\\Desktop\\img\\";
//设置背景图
final static String sourceFilePath = "C:\\Users\\liuya\\Desktop\\img\\background.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();
g.drawImage(writeH("恭喜发财"),0,0,640*4,640,null);
g.drawImage(writeV("三江进宝百业旺"),0,640,640*2,2*640*7,null);
g.drawImage(writeV("四海来财万福春"),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();
}
}
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;
}
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, 400);
FontDesignMetrics metrics = FontDesignMetrics.getMetrics(font);
Graphics2D graphics = bufImg.createGraphics();
graphics.setColor(Color.black);
graphics.setFont(font);
graphics.drawString(content, 120, 460);
graphics.dispose();
System.out.println(content);
return bufImg;
}
}启动方法：idea编辑器里运行主方法即可。
看效果，上图
合成一张图里，方便打印，剪裁,哈哈！！！
