[Insight-users] Reading and writing to a buffer

[Luis Ibanez]

HI Daniel,

Please read the Tutorials:

http://www.itk.org/HTML/Tutorials.htm

In particular:

http://www.itk.org/CourseWare/Training/GettingStarted-V.pdf

It describes how to pass buffer data in and out
of ITK images.


   Regards,


      Luis
