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, ...)

## Arguments

x |
An `im3d` object with associated voxel dimensions, a path to or a 2 x 3
BoundingBox `matrix` . |

... |
Additional arguments for methods |

dims |
The number of voxels in each dimension when x is a BoundingBox
matrix. |

## Value

A numeric vector of length 3, NA when missing.

## Details

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.
