[ITK-dev] itk::ImportImageFilter buffer

[Matt McCormick]

Hi Marco,

std::vector is usually contiguous in memory, so you can pass the
buffer directly.  However, you will want to set

  importImageFilterWillOwnTheBuffer = false;

since the std::vector will de-allocate the memory when it goes out of scope.

HTH,
Matt

PS.  Please reply-to-all so the message goes on the mailing lists.
