    行程编码的基本原理是:用一个符号值或串长代替具有相同值的连续符号(连续符号构成了一段连续的“行程”。行程编码因此而得名),使符号长度少于原始数据的长度。只在各行或者各列数据的代码发生变化时,一次记录该代码及相同代码重复的个数,从而实现数据的压缩。(The basic principle of run length coding is: a symbolic value or string length instead of having the same value of consecutive symbols that symbol length less than the length of the original data (consecutive symbols constitute a period of continuous stroke run-length encoding, hence the name.) . Only when the code for each row or each column of data is changed, the recording time code and the same number of code duplication, in order to achieve compressed data.)
