Logged as a bug; I'd write a patch if I can figure out how to do the C++ template metaprogramming magic.
I ran into this when I needed to multiply an itk::VectorImage by a scalar constant. Using the MultiplyImageFilter, the SetConstant (and SetConstant1 and SetConstant2) methods only accept InputImage1PixelType as a constant. So, because I was deep into abstruse code, my naïve solution was to instantiate an itk::VariableLengthVector as the constant to pass to SetConstant, where each element was the scalar constant. This is, upon further reflection, absurd, because A * B for vectors doesn't even make sense in matrix math, and there's no operator for pairwise multiplication of vector elements. But what I found out running my program is that itk::VariableLengthVector will instantiate an operator * with boundless recursion. There are two problems: not disallowing boundless recursion, and not supporting scalar constants for vector Images in itk::BinaryFunctorImageFilter. https://issues.itk.org/jira/browse/SIMPLEITK-498 ________________________________ Notice: This UI Health Care e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.
