Parameters
roiSize
Maximum size of the source and destination image ROI.
kernelSize
Size of the kernel in pixels.
pBufferSize
Pointer to the computed size of the buffer.
Description
These functions operate with ROI (see Regions of Interest in Intel IPP).
These functions compute the size of the working buffer required for the functions
ippiFilterColumnPipeline
and
ippiFilterColumnPipeline_Low
respectively. The buffer with the length
pBufferSize
[0]
can be used to filter images with width equal to or less than
roiSize
.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if the pointer
pBufferSize
is
NULL
.
ippStsSizeErr
Indicates an error condition if
maskSize
has a field with a zero or negative value, or if
roiWidth
is less than 1.
