[Insight-users] itkMinimumMaximumImageCalculator

[Paul Yushkevich]

Chad,

I'm not sure that my answer is right, but try doing this: change the 
names of the variables min and max to myMin and myMax.  In some 
compilers min and max are #defined macros and that may be causing the 
problem.  I know that I've had no problem using the MinMaxCalculator 
with the gcc compiler.

On the other note, I would recommend using myCalculator->Compute() 
instead of ComputeMin and ComputeMax.  It should be a little more 
efficient when you need both the min and the max.
