Convert Objects into antsImage objects

Description

Convert types to antsImage

Usage

as.antsImage(
  object,
  pixeltype = "float",
  spacing = as.numeric(seq.int(from = 1, by = 0, length.out = length(dim(object)))),
  origin = as.numeric(seq.int(from = 0, by = 0, length.out = length(dim(object)))),
  direction = diag(length(dim(object))),
  components = FALSE,
  reference = NULL,
  ...
)

## S4 method for signature 'matrix'
as.antsImage(
  object,
  pixeltype = "float",
  spacing = as.numeric(seq.int(from = 1, by = 0, length.out = length(dim(object)))),
  origin = as.numeric(seq.int(from = 0, by = 0, length.out = length(dim(object)))),
  direction = diag(length(dim(object))),
  components = FALSE,
  reference = NULL
)

## S4 method for signature 'array'
as.antsImage(
  object,
  pixeltype = "float",
  spacing = as.numeric(seq.int(from = 1, by = 0, length.out = length(dim(object)))),
  origin = as.numeric(seq.int(from = 0, by = 0, length.out = length(dim(object)))),
  direction = diag(length(dim(object))),
  components = FALSE,
  reference = NULL
)

Arguments

object	An object
pixeltype	a character string e.g. "float"
spacing	numeric vector matching image dimensionality e.g. c(1.2,1.2)
origin	numeric vector matching image dimensionality e.g. c(0,0)
direction	numeric matrix matching image dimensionality eg diag(2)
components	number of components per voxel, e.g. 1
reference	optional reference antsImage providing all header info
...	Extra named arguments passed to FUN

Examples

arr <- array(rnorm(10^3), dim = rep(10, 3))
img <- as.antsImage(arr)
i2 <- as.antsImage(arr, reference = img)
