Thread: 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
