1 ****.format就是以一定的格式返回一个字符串
2.compare就进行比较,比如自己与其它对象比较
3.C++的语言和在VC里用的语言有点不一样: 本质一样的,只是VC自己先定义了一些宏,类,或把C++的东东重新定义了.比如#define UINT unsigned int
4输入输出VC中是用得不多.因为向窗输出用SetWindowText就可以了,向文件输出用CFile.Write就可以了.
UVTools are a set of software utilities to play, convert and analyze YUV or RGB video data in their raw formats. The main features of YUVTools are: It accepts (plays, converts, edits and analyzes) the combination of following formats: YUV in 4:4:4, 4:2:2 or 4:2:0 sample format, RGB in 4:4:4 sampling format; in different component order, like YUV, YVU, UYV, RGB, BGR, etc. in progressive (one single frame) or interlaced (two fields) format; in planar (YYY...UUU...VVV...) or packed (YUV, YUV....) pixel format; in predefined or arbitrary resolutions; Support FOURCC ( refer to: http://www.fourcc.org/). An image preview function to help guess the video format interactively. YUV Player can open multiple player dialogs and play different files in each dialog separately, or play multiple video files in one player dialog one by one sequentially. The detailed format of any opened or generated files will be logged, and the user can directly select any file to play back from the history list. YUV Converter can convert any combination of the format to another format, or convert to (or from) a sequence of BMP files. Other conversion functions include: scaling, join, crop, flip, padding, merge and separation of color components. YUV Analyzer can be used to calculate PSNR between two YUV files, or compare pixel by pixel to check the difference between the corresponding frames of two files, or overlay block type or motion vectors on top of each frame. Another useful feature is to help check the motion between two adjacent frames. YUV Editor can be used to edit the images pixel by pixel, or overlay one YUV image on top of another YUV image file. Convert YUV file to AVI format or vice versa; Setting options include grid display, different YUV to RGB conversion formula, etc. Many of above functions can also be performed in command line mode, which are useful for batch process or scripting.

        VC/MFC社区版块或许是CSDN最“古老”的版块了,记忆之中,与CSDN的年龄几乎差不多。随着时间的推移,MFC技术渐渐的偏离了开发主流,若干年之后的今天,当我们面对着微软的这个经典之笔,内心充满着敬意,那些曾经的记忆,可以说代表着二十年前曾经的辉煌……
        向经典致敬,或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天,我们期待着MFC技术能够恢复其曾经的辉煌,或许这个期待会永远成为一种“梦想”,或许一切皆有可能……
        我们希望这个版块可以很好的适配Web时代,期待更好的互联网技术能够使得MFC技术框架得以重现活力,……
