HoughLineGetSize

Computes the size of the working buffer for the straight lines detection.

Syntax

IppStatus ippiHoughLineGetSize_8u_C1R(IppiSize roiSize, IppPointPolar delta, int maxLineCount, int* pBufferSize);

roiSize: Size of the source image ROI in pixels.
delta: Step of discretization (delta.rho - radial increment, delta.theta - angular increment).
maxLineCount: Number of elements of the destination buffer.
pBufferSize: Pointer to the size of the working buffer.

The function ippiHoughLineGetSize is declared in the ippcv.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function computes the size of the temporary working buffer that is required for the function ippiHoughLine.

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if pBufferSize is `NULL`.
ippStsSizeErr	Indicates an error condition if roiSize or delta has a field with zero or negative value.
