How to use color keys ?

I want to ask a question: How to use color keys ? I never hear it before!!

I used vs2005 , and the operating system is Windows XP

If you mean that trick in film (which is actually called chroma key) you just subtract the pixels of a certain color, like green, and add in the ones from your replacement image from the same coordinates. You could do it row by row of pixels. I have no idea how efficient that is though.

Why I post a new message? I just post it in that top theme

Code:

Nomally, I like use following code to build program frame
//#define BLUEGUY_MARK

#ifdef BLUEGUY_MARK

  #define chSTR2(x)  #x 

　#define chSTR(x)    chSTR2(x) 

　#define chMSG(desc)    message(__FILE__"("chSTR(__LINE__)"):"#desc)

　#define NOT_IMPLEMENT_YET chMSG(not implement yet) 

　#pragma NOT_IMPLEMENT_YET

#endif

I moved it because it was an off-topic hijack of another thread.

The colour in the post you bumped is just HTML for illustration only.

Most modern IDE's can syntax colour the code (keywords blue, comments green etc etc).
