[vtkusers] vtkImageAccumulate

[Beate Aistleitner]

hi,

thanks for all your quick responses to my first question. unfortunately
getting an histogram doesn't work with the help of your examples either. i
just get an empty window. is there anything wrong with this snippet of code?

    vtkImageReader reader = new vtkImageReader();
    reader.SetFilePrefix("H:/vtkdata/headsq/half");
    reader.SetDataExtent(0, 255, 0, 255, 1, 93);

    vtkImageAccumulate hist = new vtkImageAccumulate();
    hist.SetComponentExtent(0, 255, 0, 255, 1, 93);
    hist.ReleaseDataFlagOff();
    hist.SetInput(reader.GetOutput());
    hist.Update();

    vtkImageViewer viewer = new vtkImageViewer();
    viewer.SetInput(hist.GetOutput());
    viewer.GetRenderer().SetBackground(1, 1, 1);
    viewer.Render();

thanks for your help,
Beate
