[Insight-users] vtkview and files converted by ITK

[Luis Ibanez]

Hi Perrine,

The Example

   Insight/Examples/IO/ImageReadWrite.cxx

uses pixel type "unsigned short" in line 87.

I wonder if the pixel type that you need is
"unsigned char". You may want to try changing
the pixel type, recompiling the example and
converting your PNG images again into GIPL
and HDR.


Please let us know if you find any further
problems.


   Thanks


      Luis
