[Insight-users] Converting ITK images into Buffers and back

[Luis Ibanez]

Hi Zihua,

You can get the buffer to the image data by
calling the GetBufferPointer() method in the
ITK Image.

Please look at the Doxygen documentation of
this class at:

http://www.itk.org/Insight/Doxygen/html/classitk_1_1Image.html


You should also look at the Tutorials

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


In particular to:

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

That describes how to integrate ITK into existing
applications. Buffer conversions is the central theme
of this tutorial.


    Regards,


        Luis
