WebbRLE (Run- Length Encoding 行程长度编码)压缩算法是Windows 系统中使用的一种图像文件压缩方法, 其基本思想是: 将一扫描行中颜色值相同的相邻像素用两个字节来表示, 第一个字节是一个计数值, 用于指定像素重复的次数; 第二个字节是具体像素的值 [2]。主要通过压缩除掉数据中的冗余字节或字节中的冗余位,从而达到减少文件所占空间的目的。例如, 有一表 … Run-length encoding (RLE) is a form of lossless data compression in which runs of data (sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is most efficient on data that contains many such runs, for … Visa mer Consider a screen containing plain black text on a solid white background.

And also check the run length, i.e. if it becomes 2**bits - 1 then append it. If it exceeds that value, then our values will be rounded off to 8 bit range later. WebbIn order to run-length encode a string, you can loop through the characters in the input string. Have a counter that counts how many times you have seen the same character in a row. When you then see a different character, output the value of the counter and then the character you have been counting. If the value of the counter is 1 (meaning ...

But when you see a number in the encoded sequence, how do you know if it's the length part of the first format, or just a single, non-repeating value? It does this by using the rule that we add 128 to the length before encoding it. So any number > 128 is the byte that starts the ...
