[Insight-users] How to create an image whose pixels are, accessed via a function call

[Daniel Faken]

Carlos,

  See the recent message by Dan Mueller for some of his code to do what Bill L. is suggesting.
  The message subject is '"Image Adaptor" for compressed/non-itk::Image	object <http://www.itk.org/pipermail/insight-users/2008-October/027782.html>'.

regards,
Daniel Faken
