[ITK] [ITK-users] Imagebase:: A spacing of 0 is not allowed.

[Nicolas Gallego]

Hello Ajjwal,

It seams that you are trying to shrink you image by a rational factor
(floating point value 0.3), but the itk::ShrinkImageFilter is intendend to
shrink by integer factors.
So I guess some rounding to zero is happening in between.

If you need factor like 0.3 you should use probably the
Itk::ResampleImageFilter, and make sure to compute the output information
(size, spacing, origin and direction) yourself.

I hope it helps
