[Insight-users] how to allocate memmory to itk::Array

[Mark Foskey]

I believe you can do something like:

typedef itk::Array<int> ArrayType;
ArrayType myArray;  // no space allocated

// ...more code

myArray = ArrayType(sizeOfArray);

This will construct a new array and then perform an assignment, so it 
won't be terribly efficient.  But the whole point of itk::Array is that 
the size is constant -- allocating memory later would be changing the 
size from 0 to something else.  If you really want something that works 
like an std::vector, use itk::VectorContainer.
