[Insight-users] writing ImageRegistration1 results back to an image buffer

[Michael G]

Hi Luis,

Thanks for pointing me to the tutorial material - I read through 
GettingStarted-V - Mummifying the Buffer because that seems like what I'm 
trying to do. The end of the example ends with setting 'buffer' equal to the 
PixelContainer pointer. Will buffer now be filled with the data from the 
container? I included the end of my code below,

{
    ...
    unsigned int * my_buf = new unsigned int[ width * height ];

    OutputImageType::PixelContainer *container = 
resample->GetOutput()->GetPixelContainer();
    container->SetContainerManageMemory( false );
    my_buf = container->GetImportPointer();

    ... do stuff with my_buf.. is it filled correctly with the results from 
*container?

    return 0;
}


Thank you Luis,

Michael
