DCT变换是图像图形处理中的很重要的一个压缩算法，此文件详尽的完成了DCT变换...

Implementation for Lempel-Ziv code. Encoder and decoder are separated. The input is a file and the output is written in another file.

SharpZipLib之前叫做NZipLib，完全由 C# 开发的压缩库，支持Zip, GZip, Tar and BZip2 ，为2007年8月最新0852release版的源文件和文档说明！ Changes for v0.85.2 release Minor tweaks for CF, ZipEntryFactory and ZipFile. Fix for zip testing and Zip64 local header patching. FastZip revamped to handle file attributes on extract + other fixes Null ref in path filter fixed. Extra data handling fixes Revamped build and conditional compilation handling Many bug fixes for Zip64. Minor improvements to C# samples. ZIP-1341 Non ascii zip password handling fix. ZIP-355 Fix for zip compression problem at low levels -SharpZipLib called before NZipLib, entirely by the C# Compression library developed to support the Zip, GZip, Tar and BZip2, for in August 2007 the latest version of 0852release source files and documentation!
