Syntax
IppStatus ippiPhasePackGetBufferSize_32f (int numChannels, IppiSize dstRoiSize, int* pSize);
Include Files
ippi.h
Domain Dependencies
Headers: ippcore.h, ippvm.h, ipps.h
Libraries: ippcore.lib, ippvm.lib, ipps.lib
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. |
