- Adaptive Lossless Compression Algorithm
bcl-1.2.0
- RLE又叫Run Length Encoding，是一个针对无损压缩的非常简单的算法。它用重复字节和重复的次数来简单描述来代替重复的字节。尽管简单并且对于通常的压缩非常低效，但它有的时候却非常有用（例如，JPEG就使用它）。 RLE可以使用很多不同的方法。基本压缩库中详细实现的方式是非常有效的一个。一个特殊的标记字节用来指示重复节的开始，而不是对于重复非重复节都coding run。因此非重复节可以有任意长度而不被控制字节打断，除非指定的标记字节出现在非重复节（顶多以两个字节来编码）的稀有情况下
