[ITK-users] WarpImageFilter wrong output

[Matt McCormick]

Hi John,

The DisplacementFieldTransform can be used with the
ResampleImageFilter like any other Transform. There was a time when
the DisplacementFieldTransform was not available -- the special
WarpImageFilter class was used in this case.

HTH,
Matt
