[Insight-users] itk set\get macro

[Karthik Krishnan]

Did you subclass from itk::Object ? Lots of macros optionally print out 
debug messages  and it is printed if the option GetDebug() is true. This 
method will be inherited if you subclass from itk::Object. In other 
words, you can use most Get/Set macros only if you subclass from itk::Object
