[Insight-users] How to get a progess from an iterator?

[Luis Ibanez]

Hi Lynx,

Nope,
In practice, the progress reporting functionalities have
been implemented by using the ProgressReporter
class, and by inter-twining it in the while-loop of the
iterator.


Se for example the code in the BinaryFunctor filter

  #include "itkProgressReporter.h"

  ProgressReporter progress(this, threadId,
outputRegionForThread.GetNumberOfPixels());

  inputIt1.GoToBegin();
  inputIt2.GoToBegin();
  outputIt.GoToBegin();

  while( !inputIt1.IsAtEnd() )
    {
    outputIt.Set( m_Functor( inputIt1.Get(), inputIt2.Get() ) );
    ++inputIt2;
    ++inputIt1;
    ++outputIt;
    progress.CompletedPixel(); // potential exception thrown here
    }


This results in ProgressEvents() being invoked from the filter.
