Hello,

ippcc.h file contains declarations of color convertion primitives. I'd recommend you to start from reading manual, especially when you work with such wide SDK as IPP.

Please take a look on special data type convertion functions from image processing domains, for example

IPPAPI ( IppStatus, ippiConvert_8u32s_C1R,
(const Ipp8u* pSrc, int srcStep, Ipp32s* pDst, int dstStep,
IppiSize roiSize ))
IPPAPI ( IppStatus, ippiConvert_32s8u_C1R,
( const Ipp32s* pSrc, int srcStep, Ipp8u* pDst, int dstStep,
IppiSize roiSize ))

Regards,
Vladimir

Hello,

IPP function only converts data type and does not append any image header to that.

You can construct unified gray palette easely in your code, right?
