<br>
I have a quite large binary file (> 6 GB) which contains the data I want to<br>
visualize. I am trying to read and shrink it using vtkImageReader,<br>
vtkImageShrink3D and vtkMemoryLimitImageDataStreamer.<br>
The code is listed below.<br>
<br>
vtkImageReader reader = vtkImageReader.New();<br>
reader.SetDataScalarTypeToSignedChar();<br>
reader.SetDataExtent(0, extent[0], 0, extent[1], 0, extent[2]);<br>
reader.SetDataSpacing(spacing[0], spacing[1], spacing[2]);<br>
reader.SetFileDimensionality(3);<br>
reader.SetFileName(filePath);<br>
<br>
vtkImageShrink3D shrink = vtkImageShrink3D.New();<br>
shrink.SetShrinkFactors(shrinkFactor, shrinkFactor, shrinkFactor);<br>
shrink.AveragingOn();<br>
shrink.MedianOn();<br>
shrink.SetInputConnection(reader.GetOutputPort());<br>
<br>
vtkMemoryLimitImageDataStreamer limitStreamer =<br>
vtkMemoryLimitImageDataStreamer.New();<br>
limitStreamer.SetInputConnection(shrink.GetOutputPort());<br>
limitStreamer.SetMemoryLimit(memoryLimit);<br>
limitStreamer.UpdateWholeExtent();<br>
<br>
But when I am loading file I am getting a runtime wornings and errors and<br>
the object loads partially (sometimes just several slices). I couldn't solve<br>
the problem by increasing shrink factor or memory limit. I also checked<br>
extent, dimensionality and spacing, but result was the same.<br>
<br>
Could you please help me.<br>
