bool HxImgFtorKernelNgb2d< DstImgSigT, SrcImgSigT, KerImgSigT, NgbT >::probeOp (  HxTagList &    tags )  const [virtual]
 

Probe for border size.

Reimplemented from HxImgFunctor.

00047     NgbT ngb(tags);
00048     HxSizes borderSize = ngb.size() / HxSizes(2,2,2);

Do it.

Parameters:
dstPtr  Output image: IS = dstSize, IBS = 0
srcPtr  Input image: IS = srcSize, IBS = taglist(borderSize)
kerPtr  Input image, IS = kerSize, IBS = 0
Calls HxFuncKernelNgbOp2dDispatch to dispatch the actual work.
