[Insight-users] getbuffered region

[yasser salman]

Hi Dan,
Thanks for your support, continuing to the converting "Registration Example"  found in ITK  to MangedITK code  i have so many uncompleted steps :

how can i convert 

 (1)  registration->SetFixedImageRegion( fixedImageRegion ); 
       to MangedITK
        i can't find any member (function or objects) to set *fixedimageRegion* in  MangedITK class itkImageRegistrationMethod 
(2) how can i get the number of pixels inside region
in itk:           constunsignedintnumberOfPixels = fixedImageRegion.GetNumberOfPixels();
                          but i can't corresponding in      itkImageRegion ;
(3) 
 
optimizer->AddObserver( itk::IterationEvent(), observer );
 
Thanks
Yasser

itkImageBase image = itk.itkImage_UC3.New(); // you need to create the
correct image type here...
fixedNormalizer.GetOutput(image);
itkImageRegion region = image.BufferedRegion;

itkArray<double> initialParameters = new itkArray<double>(
transform.NumberOfParameters );
initialParameters[0] = 0.0; // Set the initial parameters as desired
...
transform.Parameters = initialParameters;

Hope this helps.

Cheers, Dan
