ind2coord: Find XYZ coords corresponding to 1D indices into a 3D image

In jefferis/nat: NeuroAnatomy Toolbox for Analysis of 3D Image Data

Find XYZ coords corresponding to 1D indices into a 3D image

Description

If you have an image-like object and you want to turn it into a matrix of 3D coords then you need ind2coord. For the reverse operation we offer as.im3d.matrix which allows you to turn a matrix of 3D coordinates into an im3d image object.

Usage

ind2coord(inds, ...)

## Default S3 method:
ind2coord(inds, dims, voxdims, origin, ...)

## S3 method for class 'array'
ind2coord(inds, voxdims = NULL, origin = NULL, ...)

## S3 method for class 'im3d'
ind2coord(inds, voxdims = NULL, origin = NULL, ...)

Arguments

inds	indices into an image array (either 1D, for which dims must be present, or a logical array).
...	extra arguments passed to methods.
dims	dimensions of 3D image array.
voxdims	vector of 3 voxel dimensions (width, height, depth).
origin	the origin.
