【文本与二值图像的游程】1. 文本游程压缩的原理 对重复字段采用3符号标识法:(1) 重复提示符,比如@,#等;(2) 游程长度参数或重复次数,若用一个字节表示,最大长度可为255个重复字;(3) 重复字符。以上三部分合称为重复因子。可见要获得压缩效益,重复字符应在3个以上。2. 图像游程压缩的原理 对于二值图像,原始数据为零一矩阵,压缩时逐行处理该矩阵:(1) 连续n个1,表示为+n;(2) 连续n个0,表示为-n。-text and binary image-- an outbound trip. Yu Cheng text compression principle on repeated field using three symbols logo Act : (a) repeat prompt, such as @,#, etc.; (2) Run-length parameters, or the number of repeat, if using a byte, the largest the length of 255 to repeat the word; (3) repeat characters. More than three as part of a repeat factor. Visibility to gain compression efficiency, duplication of characters in three more. 2. Run-image compression for the principle of two binary images, a zero original data matrix, progressive compression deal with the matrix : (1) n a row, n; (2) consecutive n 0, expressed as-n.

本程序采用了最简单的方块编码对512×512的lena图像进行了编码.运行程序后可以看出,方块取得越大,图像编码后失真越大。-This procedure uses the most simple code box 512 × 512 on the lena image coding. After running the program we can see that the box to obtain the greater the greater the distortion image is encoded.

仿WinRar解压缩VB版
这个示例就是利用这个动态链接库进行的一些操作,但目前还没有压缩文件的功能,里面的dll函数接口还需要进一步的解析和查找资料,官方好像也没有提供,希望有知道的网友也可以提供一下。更希望感兴趣的网友继续进行挖掘和开发。
源代码附有详细的注释和文档说明。使用前请把压缩包里的 UnRar.dll拷贝到你的计算机的系统文件夹下,如 WindowsSystem32下。-WinRar imitation extract VB version of this example is the use of the dynamic link library to carry out some operation, but it has not been compressed files, inside the dll interface function need further analysis and search for information, the official did not seem to offer hope to have users know that you can provide. Also hope that users are interested in continuing to carry out excavation and development. Source code with detailed notes and documentation. Please use the pre-compression of the bag UnRar.dll copy to your computer s System Folder, such as under WindowsSystem32.
