[vtkusers] WG: vtkimagewriter

[Michael Knopke]

Hi Anne-Laure,
 
Sorry to answer so late, maybe you have solved your problem already.
I'm a bit confused of what you are trying to do. You write that you want to
visualize image_bin (which should be a volume) and in the other mail you
wrote that vtkImageWriter fails. So that are two different things. I'd
suggest trying to visualize either the volume (vtkFixedPointVolumeRenderer)
or a slice (vtkImageReslice) first, to see if your thresholding worked.
After that write it to disk, using vtkImageWriter. Or did I miss the point?

Hi,
So, Sorry, I wasn't very precise. I send the code :
imge3Dvtk=vtkImageReader()
imge3Dvtk.SetFileDimensionality(3)
imge3Dvtk.SetFileName("myscan.raw")
 
imge3Dvtk.SetNumberOfScalarComponents(1) #scala de grises
imge3Dvtk.SetDataScalarTypeToShort() # 2 bytes por boxel
imge3Dvtk.SetDataExtent(0,511, 0, 511, 0, 62)
imge3Dvtk.GetDataExtent()
ExportToArray = vtkImageExportToArray()
ExportToArray.SetInput(imge3Dvtk.GetOutput ())
imagen = ExportToArray.GetArray()
 
 
# 1) Use a threshold to segment the background     
imagen_bin =(imagen<-200) 
 
And there, I'd like to visualize imagen_bin. 
I suppose that it's not too difficult but I didn't know the vtkImagewriter
syntax.
 
thank you very much,
 
Anne-Laure
