[Insight-users] How To Specify PixelContainer for the output of a Filter

[Karthik Krishnan]

Assuming you are writing your own filter, if you aren't subclass the filter
in question...

First create an itk::Image with the right metadata and with a pixel
container that points to your pixel buffer. I suppose you know how to do
that, if not, please look at Examplse/DataRepresentation/Image/Image5.cxx

Reimplement the GenerateData method and force it to use your

GenerateData()
{
  this->GetOutput()->GraftOutput( this->MyImage )

  .. // rest of the generate data method
}
