TrueDistanceTransformGetBufSize

Calculates the size of the temporary working buffer for the function ippiTrueDistanceTransform.

Syntax

IppStatus ippiTrueDistanceTransformGetBufferSize_8u32f_C1R(IppiSize roiSize, int* pBufferSize);

Include Files

ippcv.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h, ippi.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib

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.
