Shouldn't there be a range check somewhere? You allow INT_MAX (could be
NPPI_INTER_NN .. NPPI_INTER_CUBIC, assuming they are contiguous), and
pass the value directly to nppiRotate_8u_C1R(). I can't tell whether
that function does a proper check and error indication though, which
could suffice.
Cheers,
Moritz
