参考网上的资料写的gif编解码。 编码用gdi解析常用图片格式，然后组装成gif 解码吧gif的每一帧转换成dib gif文件格式网上有很多介绍 gif用的变长lzw压缩算法： 没弄懂原理，只知道过程。压缩取一个字符作为后缀，看看字符串是否存在。存在，用对应的编码作为前缀继续取；不存在把字符串添加到字典，前缀添加到输出流，后缀作为前缀继续取。解压取一个编码看看字典中是否存在。存在用对应的字符串的第一个字符作为后缀，看看当前字符串是否存在，不存在添加到字典中，后缀作为前缀，前缀对应的字符串添加到输出流，继续取；编码不存在，前缀对应的字符串的第一个字符作为后缀（这时当前字符串肯定不存在，字典中下一个可用编码肯定等于刚取出的编码），字符串添加到字典中，编码作为前缀，前缀对应的字符串添加到输出流，继续取。 编码流转换成字节流是按位从低到高的，window是小端模式（低字节在低地址），字节内低位在右边。 24位dib转换成8位dib时使用的八叉树算法 图片拉伸时参考的网上的双线性插值算法。 字典满了位数加一，位数是12时不加(Online reference materials written gif codec. Encoded using gdi resolve common image formats, and then assembled into a gif Each frame decode it into a gif dib There are many online gif file format introduced gif lzw with variable length compression algorithm: Did not understand the principle, only know the process. Compression takes a character as a suffix, and see if there is a string. Exist as a prefix to continue to take with the corresponding encoding there is no string to add to the dictionary, a prefix added to the output stream, the suffix as a prefix to continue to take. Take a look at extracting coding dictionary exists. Exist with the corresponding first character string as a suffix to see the current string exists, there is no add to the dictionary, the suffix as a prefix, the corresponding string to the output stream, continue to take coding does not exist, prefix corresponding first character string as a suffix (when the current string certainly does not exis)

说明：  随着业务的不断发展，公司员工的不断增加，职工档案及工资的管理已经成为公司管理中的重要部分，传统的管理制度已经不能有效地管理员工的情况。本系统是为了方便职工档案的管理而开发的基于Visual C++的数据库应用软件。(With the continuous development of business, the continuous increase of employees, the management of employees' archives and wages has become an important part of the management of the company. The traditional management system can not effectively manage the situation of the employees. This system is a database application software developed on the basis of Visual C++ for the convenience of staff files management.)
