[Insight-users] How to use C/C++ memory operations with ITK?

[Luis Ibanez]

Hi Steven,

You can get access to the pixel buffer of the ITK
image by calling:


        image->GetBufferPointer();


However, you should be *VERY* sure of what you are
doing.

Note for example, that if the image is the output
of a filter, then all the changes that you make
will be lost as soon as the filter reruns.

The memory buffer is *ALREADY* allocated by ITK,
so you don't need to use malloc or new.

It seems that you should read the Tutorials:

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


In particular:

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


This tutorial describes multiple ways of integrating
ITK with existing applications, in particular by
passing the pointer to the pixel buffer back and forth
between ITK and your application.


You will also find useful to read the ITK Software Guide


    http://www.itk.org/ItkSoftwareGuide.pdf


In particular Section 4.1 on "Image", "Data Representation".



    Regards,


       Luis
