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 pointerpBufferSizeisNULL.
- ippStsSizeErr
- Indicates an error condition ifmaskSizehas a field with a zero or negative value, or ifroiWidthis less than 1.
