[ITK-users] what is the best way to do TriangleMeshToBinaryImageFilter on a region

[Dženan Zukić]

Hi Leon,

have you tried using RegionOfInterest
<https://itk.org/Doxygen/html/classitk_1_1RegionOfInterestImageFilter.html>
instead of ExtractImageFilter? Extract is used for changing image
dimension, e.g. extracting a 2D slice from a 3D volume.

Regards,
Dženan
