[Insight-users] question for using pointset

[Zhiyong Xie]

I have a question for using class PointSet to define Landmarks.
In code "itkSplineKernelTransformTest.cxx", function "Reserve()"
was used to reserve the memory. Is it necessary to allocate the
memory?
Another related question is for the function of "GetNumberOfPoints()",
is the number it returns the actual number of points I added, or the
number I used in "Reserve()"?

Thanks
