[Insight-users] const question according to itkSegmentationLevelSetFunction

[Christoph Palm]

Hi all,

is there a good reason, that the function

GetSpeedImage()

is non-const, whereas e.g. the function

GetAdvectionImage() is a const-function?

In the const function PropagationSpeed(...)
a pixel value of m_SpeedImage is returned via
m_SpeedImage->GetPixel(idx)
which would result in a compiler error, if this
would be done via
this->GetSpeedImage()->GetPixel(idx).

Thanks for clarifications.

Christoph
