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. |
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.
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. |
