Extract Subset filter strange behaviour
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I have an image dataset A (1137x716x834) that was created using the Extract Subset filter from a larger dataset. It is stored in a .pvti + 8*.vti files. The extents of A are
X: 514-1650 (dim 1137), Y: 455-1170 (dim 716), Z: 0:833 (dim 834)
I want to create a subsampled version of A by once again using the Extract Subset filter, with as VOI the full extents above and setting its sample rates to 2. But to my surprise the subsampled dataset (using PV 3.10.1 in standalone mode, btw) ends up having extents
X: 514-825 (312), Y: 455-584 (130), Z: 0-416 (417)
and covers only the upper portion of A, not the whole set. I also don't understand where the weird reduction in X and Y dimensions comes from (factors 3.6 and 5.5, resp). See the attached screenshots.
