Parameters
roiSize
Size of the image ROI in pixels.
pBufferSize
Pointer to the computed size of the buffer.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function calculates the size of the work buffer required for the TrueDistanceTransform function.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize
has a field with zero or negative value.
ippStsStepErr
Indicates an error condition if
srcStep
or
dstStep
is less than
roiSize.width*<pixelSize>
.
ippStsNotEvenStepErr
Indicates an error condition if step value is not divisible by 2 for
16u
images, and by 4 for
32f
images.

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.
