[Insight-users] Byte Order Swapping??

[Luis Ibanez]

Hi Neha,

1) ITK does not have any endianess default.

2) The DiscreteGaussianFilter does not alter
    the endianess of an image.

3) Endianess is a property of the platform you
    are using.

4) ITK image filters are unaware and independent
    of the endianess used by your platform.

The only classes in ITK that deal with endianess
are the ImageIO classes. Among them you seem to
be using the RawImageIO class.

Please *DON'T* use raw images. Raw images are
dangerous due to their lack of fundamental
information about the image content.

If you have raw files, please write MetaImage
headers for them and use the standard ITK
ImageFileReader and ImageFileWriter to read
and write images. This is illustrated in almost
all the examples in

            Insight/Examples

and their associated descriptions in the
software guide:
