Parameters
numChannels
Number of channels in the image. Possible values are 1 and 3.
dstRoiSize
Size, in pixels, of the destination image ROI.
pSize
Pointer to the computed size of the external work buffer, in bytes.
Description
The
ippiPhasePackGetBufferSize
function computes the size, in bytes, of the external work buffer needed for the
ippiPhasePack
function. The result is stored in the
pSize
parameter.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when
pSize
is
NULL

ippStsSizeErr
Indicates an error when
dstRoiSize
has a field with a value less than 1.
ippStsNumChannelsErr
Indicates an error when
numChannels
has an illegal value.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
