不多废话,先上几张效果图:
其实也是闲着无聊,偶然间看到网上一篇博客,介绍了window10的cmd可以使用 ANSI转义显示彩色字或背景(点我查看学习资料),感觉突然来了点灵感,cmd的黑白控制台尽然也可以显示这么多颜色!那我是不是可以拿它来画画了!哈哈,所以就有了下面的尝试.直接上java工具代码:

注释写的还算可读,稍微解释一下原理,首先CMD部分的原理很简单,就是一些特殊的ANSI转义字符可以显示彩色的背景,因此可以在控制台打印出彩色的空格,这个是基础,可以参看上面的链接自己尝试.
然后就是需要告诉控制台我要在哪些地方输出什么颜色的字符,输出多少,说白了就是要解决画画的问题.这一步我采用java实现,我们使用BufferedImage
读取一张图片,然后按照我们设定的扫描像素,一格一格的识别图片中的RGB色值,并且我们将图片的RGB色值与控制台可以输出的颜色做一个对比,找到最接近的那个颜色,打印出来就可以了.
因为控制台支持的颜色比较少,只有16种,因此我们是没办法完美的输出图片中的颜色的,所以这边我采用简单的一种类似方差的概念去判断图片中的颜色和哪个控制台颜色最接近,这可能是关键代码了吧(请忽略颜色的中文命名,为了好记).
使用过程中需要注意的点就是:
@echo off
echo [40m 40
echo [41m 41
echo [42m 42
echo [43m 43
echo [44m 44
echo [45m 45

echo [47m 47
echo [100m 100

echo [103m 103
echo [104m 104
echo [105m 105
echo [106m 106

pause
最后附上几张像素图和对应已经转化好的代码,大家有兴趣的可以自己再桌面上运行看看_.
