[Insight-users] short format

[Luis Ibanez]

Hi John,

The code should become

>   typedef short               InputPixelType;
>   typedef short       OutputPixelType;
>   const   unsigned int        Dimension = 3;
>
>   typedef itk::Image< InputPixelType,  Dimension >    InputImageType;
>   typedef itk::Image< OutputPixelType, Dimension >    OutputImageType;
>   typedef itk::ImageFileReader< InputImageType  >  ReaderType;
>
>   typedef short        InputPixelType_extract;
>   typedef short        OutputPixelType_extract;
>   typedef itk::Image< InputPixelType_extract,  3 >
> InputImageType_extract;
>   typedef itk::Image< OutputPixelType_extract, 2 >
> OutputImageType_extract;


and you could use as output file
format any of the following:

* MetaImage ( extension .mha)
* VTK (extension .vtk)
* Nifty (extension .nii)
* Nrrd (extension .nrrd)

They all support "short" as a pixel type.

You can view any of this format
with the SNAP, Slicer, VV, and
the simple ImageViewer in
InsightApplications.
