GifCodec
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)

RdWrtIni
说明: ini文件读取和写入,基于MFC实现的。因为Wince下没有实现ini文件的读写。(ini file to read and write, based on the realization of the MFC. Wince achieve because there is no read and write ini files.)

Date-increment-1
自定义一个简单的日期类DateType,它具有数据成员y、m、d,用来表示当前日期的年、月、日。而后设计该类欲实现(完成)的功能,进而设计出相应的类成员函数。
例如,下面给出的“雏形”可用来实现对天的增加,比较两个日期是否相等,以及对日期的输出等操作。请完成各类成员函数,并编制主函数,说明DateType类对象,对定义的各成员函数进行调用,以验证它们的正确性。
(Customize a simple date class DateType, it has a data member y, m, d, is used to indicate the current date, month, and day. To achieve the latter design class (complete) function, and then design the appropriate class member functions. For example, the following is the " prototype" is used to achieve the increase of day, compare two date are equal, and the output of dates and other operations. Please complete all kinds of member functions, and prepare the main function, indicating DateType class object for each member function definition be called to verify their correctness.)
