[Insight-users] Casting or accesing data from typedef float to just float

[Luis Ibanez]

Hi Bios5,


Please read the Tutorials

       http://www.itk.org/ITK/help/tutorials.html

in particular

   "Getting Started V: Integrating ITK in your Application."

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


Your will find that you have multiple options for passing output
data from ITK into your application (Osirix plugin in this case).


You can:


   A) pre-allocate the output buffer and give it to the last
      ITK filter in the pipeline.


or


   B) Disconnect the output image of the last filter and
      Mummify its buffer, and then pass it to your application
      (in which case you become responsible for releasing the
       memory at some later time).



You will find descriptions of both methods in the tutorial above.


    Regards,


        Luis
