Convert Objects into antsImage objects

Convert types to antsImage

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 class '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 class '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)
