| The ResampleImageFilter produces concept checking errors if you try to use it with a vector image. The VectorResampleImageFilter must be used instead, as demonstrated in this example. | | {{warning|1=The media wiki content on this page is no longer maintained. The examples presented on the https://itk.org/Wiki/* pages likely require ITK version 4.13 or earlier releases.
