Half border pixels in viewer

Wanting to understand why there are thin/half border voxels in the viewer, I filled this bug report 3 months ago. Moreover, I just found the ImageMapToColors example which shows the same behavior. tl;dr as we can see in this image, only the half of the border voxels is visible.


Is there a way to disable that “feature”? What the rationale behind this decision?

Image data values are point samples at the center of each voxel. You can enable/disable half-voxel extrapolation over the first/last sample using Border property of the image mapper.
