[vtkusers] From vtkImageData to Iplimage (OpenCV)

[alex Dowson]

Hi

void fromIpl2Vtk( IplImage* _src, vtkImageData* _dest )
{
    vtkImageImport *importer = vtkImageImport::New();
    if ( _dest )
    {
        importer->SetOutput( _dest );
    }
    importer->SetDataSpacing( 1, 1, 1 );
    importer->SetDataOrigin( 0, 0, 0 );
    importer->SetWholeExtent(   0, _src->width-1, 0, _src->height-1, 0, _src->nChannels-1 );
    importer->SetDataExtentToWholeExtent();
    importer->SetDataScalarTypeToUnsignedChar();
    importer->SetNumberOfScalarComponents( _src->nChannels );
    importer->SetImportVoidPointer( _src->imageData );
    importer->Update();
}

I've worked with Ipl images before , if I'm not wrong the easiest way to do that is writing directly the scalars from vtkImage to Iplimage. sure I'm missing some details but the this is the idea. Sorry I can't help you more.

  Hey all,

  Has anyone figured out how to convert a vtkImageData to an image I can work
  on OpenCv.
  Basically I render something on the screen and I want to apply some OpenCV
  algorithms to it.

  Thanks in advance :)

  Nacho
