[Insight-users] Enlarging an image

[Francis Girard]

Thank you very much,

I see that the transform is set to identity. Nonetheless I guess there is a
resize transform simply by specifying the output size with the resampler
SetSize method.

Interpolation will be executed as specified by the SetInterpolator method.
So I just have to put the BSplineInterpolateImageFunction there.

I don't think that spacing (input or output) is used for the rescale by the
resampler. It just stays at the level of meta information. Right ?

That helped very much, thank you
