# VC编程实现色彩空间XYZ与LAB相互转换 #

文章[VC编程实现色彩空间RGB与XYZ相互转换][VC_RGB_XYZ]已经介绍了RGB与XYZ色彩空间的转换算法以及实际的VC源代码，在上一篇文章已经提到，在PhotoShop中经常使用有RGB(红色、绿色、蓝色)、CMYK(青色、洋红、黄 色、黑色)、HSB(色相、饱和度、亮度)和Lab4中色彩空间。我们用到XYZ色彩空间的目的是进行RGB与LAB色彩空间转换的中介，承接前文，本文将介绍XYZ与LAB色彩空间之间的转换方法，并列出具体的算法公式和VC源代码。

REF\_X 、REF\_Y 、REF\_Z 是参照白点CIE XYZ三色刺激值，与色彩空间XYZ转LAB的取值一样。到此，便使用VC编程实现了色彩空间LAB到XYZ的转换，本文介绍了LAB色彩空间与XYZ色彩空间的正变换和逆变换，结合前文，便实现了RGB->XYZ->LAB色彩空间的变换，同样也可以实现LAB->XYZ->RGB逆变换。为方便读者理解，给出了具体的计 算公式和实际源码。VC图形图像处理编程博大精深，有任何建议欢迎留言讨论，后续文章我们将继续介绍VC编程实现其它色彩空间之间的相互转换。

本系列程序均在Win7+VS2008测试通过，并且结果与PS3的运算结果一致。
