[Insight-users] Pixel value

[Luis Ibanez]

Hi Camilo,

If you need to convert the pixel value to another type
you can simply use static_cast< type >( pixelValue ).

Note however, that the C-language casting rules will apply.

For example, if the PixelType is actually  float and
you cast it to int, then you will lose information from
the pixel value, like in


    int value = static_cast< int >( myIterator.Get() );


It is your responsibility to make sure that the recipient
type (the int or the double) are capable of storing the
input value without loss of precision.


Regards,


     Luis
