有谁会用ASCII画图？ 有相应算法没？(200分)

就像上面这个（能看出是什么东东吗？）

好像有软件可以把图片转化为ASCII Graph的，
挺想做一个玩玩儿的（是不是有点自不量力）？
有啥思路可供参考，具体和抽象都行，不限发挥。

能提供源码的或是带源码组件的俺另外给分啦。

如果使用单一字符, 可以吧图像读入image, 再根据canvas.cells
打出ascii 图像. 只是太单调了,
如何决定使用那个字符? 使用多种字符的图像, 才会有效果
洗耳恭听,
要么, 你可以作一个工具, 提供画布, 让人来华,
如:
用image现实图片, 在上面描上网线, 就可以用鼠标或键盘
对照在相应的方格内填上适当的字符. 然后把他保存为ascii 文本
文件

猜得出这是谁吗？

巩利?
真不错, 自己画的? 累坏了?

好玩儿，再来几个！

`

是呀，单一字符的东西我写过，把图片先锐化的不能锐化，再转化为二值图像，然后......做出来的好恶心呀。 不过写一个画板倒是不错的主意，可惜对我这样的画盲还是没用。

关键是算法，谁有？C源码也成！

好像有现成的软件的,到国外的大下载站点找找看,我以前见到过.

感兴趣

刚发现了一个有C源码,但下载连接坏了，待下载好测试过再汇报.

算法不算难吧?
其实思路很简单嘛.
可以将一个可打印字符认为是由9格组成的brush, 比如"`", 就是左上角是黑色
其他部分是白色的brush, 将所有可打印字符做成不同的brush, 然后分割要
转换的图象, 比较每块, 套用不同的brush填入呗.

呵呵，有趣，继续

下面是一个VC的例子,抄别人的.

分分呢?
