C++ 如何设置像素的颜色？

setpixel.

1、 获取屏幕DC

HDC hDC = ::GetDC(NULL); //获取屏幕DC
2、 获取当前鼠标位置像素值

CPoint pt;
GetCursorPos(&pt); //得到当前鼠标所在位置
COLORREF clr = ::GetPixel(hDC, pt.x, pt.y); //获取当前鼠标点像素值
3、 分解出像素点中的红、绿、蓝颜色值

CString ClrText;
ClrText.Format("%d",GetRValue(clr)); //分解出红色值
ClrText.Format("%d",GetGValue(clr)); //分解出绿色值
ClrText.Format("%d",GetBValue(clr)); //分解出蓝色值
::ReleaseDC(NULL, hDC); //释放屏幕DC

话问得有问题，GDI? SDL? OGL? DX?
