This would properly be thought of as the voxel spacing when voxels are assumed not to have a physical extent (only a location).
voxdims(x, ...) # S3 method for im3d voxdims(x, ...) # S3 method for character voxdims(x, ...) # S3 method for default voxdims(x, dims, ...)
Additional arguments for methods
The number of voxels in each dimension when x is a BoundingBox matrix.
A numeric vector of length 3, NA when missing.
We follow Amira's convention of returning a voxel dimension equal to the bounding box size (rather than 0) for any dimension with only 1 voxel.
