[Insight-users] use of std::vector with ITK typedefs

[Arvind Rao]

Hi all,

In order to read-in a variable number of points from a file I want to use a
dynamically sized container like STD::VECTOR. The points are stored like
so: ( *points is the vector I use* )

      typedef itk::Image< itk::Vector<ComponentType, Dimension>, Dimension>
                                PeakImageType;
      typedef PeakImageType::PixelType
                                                         DirectionType;
      *std::vector<DirectionType>
                                                                 points*
*
*
However, the following try-catch statement gives, at run-time,* "bad_alloc
caught: St9bad_alloc"*

*      *try
      {
                std::vector<DirectionType> points;
                ReadStreamFile<DirectionType>( streamArg.getValue(), points
);
      }
     catch (std::bad_alloc& ba)
      {
                std::cerr << "bad_alloc caught: " << ba.what() << std::endl;
                return 0;
      }

So, what is going on? Its seems like POINTS is not being allocated
properly, but I'm sure how to fix this.

Thanks for any help you can provide.
