[vtkusers] about image orientation

[ivan gm]

Hi:

Maybe you want to use itkOrientImageFilter, it lets you to orient 2D and 3D
images like in mimics:

#include "itkOrientImageFilter.h"
typedef itk::OrientImageFilter<ImageType,ImageType> OrientImageFilterType;
OrientImageFilterType::Pointer orienter;
orienter->SetUseImageDirection(true);
orienter->SetDesiredCoordinateOrientation(itk::SpatialOrientation::ITK_COORDINATE_ORIENTATION_RPI);
orienter->SetInput( Reader->GetOutput() );
orienter->Update();

Regars.
Iván Yerak.
