终于把project1做完了！！part3和part4真是debug到死啊。。
用这个RLE压缩算法可以把164kb的tiff图片文件 ...

大神你好！ 我现在正在做这个pj得part2 卡在一个地方了，能不能麻烦你把你的代码（如果还在的话）发到我的邮箱，我想借鉴一下，万分感激！ senyangzhuang@163.com

Part 2 - 3 像素图像和行程编码之间的互相转换。  Part 4：编写函数：给出像素坐标和新值，直接修改对应的 ...

求问大神， part2里面得两个RunLengthEncoding得构造函数是什么意思啊？ 是要我们构造一个DList来储存嘛？ 连题目都看不懂 真是要跪了。。

Project 1 part I 的執行結果如下圖所示 (這個作業還蠻花時間的, 不過終於有時間去抓奇樂了)

以下為part II-IV結果 (圖片太多, 分2樓上傳)

请问jai那个怎么导进去啊？就是jai_codec.jar和jai_core.jar？谢谢了

各位大牛，转专业新人有一个问题想问一下， 我已经把part1的code 写好了，可是不清楚怎样读取tiff图片文件 ...

请问jai_codec.jar和jai_core.jar下载下来放在哪啊？谢谢

樓上的朋友, 如果你用的是eclipse
可以參考一下下面圖示的
