[ITK] [ITK-users] Vectorize/Linearize itk::Image

[Lowekamp, Bradley (NIH/NLM/LHC) [C]]

Hello,

You want to look at the ImportImageContainer[1]. Every itk::Image has one of these object to hold the buffer. The fastest way to “convert” the image, is not to do any work and just get a pointer to the buffer.

HTH,
Brad
