16sc_C1RSfs

[siddy]

Hi all,
In the documentation for IppAddC_<>, one of the acceptable image data format
is 16sc_ . I was wondering
1) How can one allocate a 16sc image through ippiMalloc ? I am not able to find 16sc_C1R as
a possible modifier in ippiMalloc documentation (I am using 6.1)
2) Is it possible to construct a 16sc image using 2 16s images? How should this be done? I was
assuming RealToCplx, but that exists only for ipps (vector) data

Thanks,
Sid.
