[Insight-users] Resampling an image after a rigid body 3D registration

[Vincent A. Magnotta]

Remi,

The ResampleImageFilter takes an ITK transform as well as an image to
resample. You should be able to simply take your transform (assuming
that the transform was created in ITK) and call the SetTransform method
for the class.
