depressed. After a few days a year, it seems that there is no feeling. The lively time is not long enough, it is very unhappy. Tomorrow is 2.14 Valentine's Day. Um ... I don't care what I do. It is a person at home tomorrow night, find something entertainment? no. It's a few ... WAR3, Coding, Film, TV, Music ... etc. Looking at the frame gradually developed, it feels very cool ~~ This time, what should I always make something? Come. Code on the code. If this blog has a keyword, it is fine. . .

It's roughly like this, there are several functions in the middle to copy from Microsoft's ddutil.cpp, just less DD two characters.
A function of reading the tones from the Bitmap file, because I plan to do the Game is at least 24bit colors, with a palette.
16bit colors should be judged that 555, 565 is very troublesome. Needless, then 65536 colors are too small, it is not conducive to the beauty of the art ...
