黑客帝国-代码雨
一黑客帝国-代码雨
下载地址
http://www.tyyishundan.top/cmatrix-1.2a.tar.gz
wget http://www.tyyishundan.top/cmatrix-1.2a.tar.gz
- 也可手动下载
安装
tar xf cmatrix-1.2a.tar.gz
cd cmatrix-1.2a
yum install -y ncurses-devel
./configure && make && make install
主要前面的点
使用
cmatrix
二 彩色字体特效
下载地址
http://www.tyyishundan.top/lolcat-master.zip
wget http://www.tyyishundan.top/lolcat-master.zip
unzip lolcat-master.zip
cd lolcat-master/bin/
安装
gem install lolcat
报错 -bash: gem: 未找到命令
没有下载安装gem 直接yum下载安装就好了
yum install -y gem
再次安装就好了
用法
使用|连接
例：
echo "I love you"|lolcat
输出的I love you为彩色字体

1.代码（html）：

var columns = canvas.width/fontSize;
// 用于计算输出文字时坐标，所以长度即为列数
