Extract Geometric Properties of an Image
Description
This function retrieves the geometric properties of a given image, such as dimensions and voxel size.
Retrieves the NeuroSpace object associated with an IndexLookupVol object.
Usage

## S4 method for signature 'IndexLookupVol'
space(x)
## S4 method for signature 'ROICoords'
space(x)
## S4 method for signature 'NeuroObj'
space(x)
## S4 method for signature 'NeuroSpace'
space(x)

Value
A NeuroSpace
object representing the geometric space of x
.
Examples
# Create a NeuroSpace object with dimensions (10, 10, 10) and voxel size (1, 1, 1)
x <- NeuroSpace(c(10, 10, 10), c(1, 1, 1))
# Create a NeuroVol object with random data and the specified NeuroSpace
vol <- NeuroVol(rnorm(10 * 10 * 10), x)
# Retrieve the geometric properties of the NeuroVol object
identical(x, space(vol))
space <- NeuroSpace(c(64, 64, 64), c(1, 1, 1), c(0, 0, 0))
ilv <- IndexLookupVol(space, c(1:100))
space(ilv) # Get the associated NeuroSpace object
