Constructor & Destructor Documentation

HxMfKernelNgb::HxMfKernelNgb (  HxImageData *    srcImg,
HxImageData *    kernel,
HxString    ngbName,
HxTagList &    tags
) 
 

Constructor.

A result image will be allocated with the same size as the source image. The registry will be queried for the result type. The registry will also be queried for the kernel type. If necessary the kernel image will be converted to this type. 

00021     : _source(srcImg), _kernel(kernel), _result(0),
00022         _tmpKernel(0), _preOpIsOk(true)
00023 {
00024     if (!_source || !_kernel)
00025     {
00026         _preOpIsOk = false;
00027         return;
00028     }
00029

00031 
00032     HxImageSignature resultSig
00033         = HxImgFtorRuleBase::instance().getResultType(
00034             srcSig, "kernelNgb", srcSig.toString(), ngbName);
00035 
00036     HxImageSignature kernelSig
00037         = HxImgFtorRuleBase::instance().getKernelType(
00038             _kernel->signature(), "kernelNgb", srcSig.toString(), ngbName);
00039 
00040     _result = HxImgDataFactory::instance().makeImage(resultSig, srcImg->sizes());
00041 
00042     if (kernelSig != _kernel->signature())
00043     {
00044         _tmpKernel = HxImgDataFactory::instance().makeImage(
00045             kernelSig, _kernel->sizes());
00046         _tmpKernel->setPartImage(_kernel);
00047         _tmpKernel->weight(_kernel->weight().x());
00048         _kernel = _tmpKernel;
00049     }
00050 }

HxMfKernelNgb::~HxMfKernelNgb (    ) 
 

Destructor. 

00053 {
00054     if (_tmpKernel)
00055         delete _tmpKernel;
00056 }
