antsImage-class: An S4 class for an antsImage

Description

C++ type used to represent an ITK image pointed to by 'pointer'. the actual image is of C++ type 'itk::image< pixeltype , dimension >::Pointer'

Usage

# S4 method for antsImage
show(object)
# S4 method for antsImage
initialize(.Object, pixeltype = "float",
  dimension = 3, components = 1)
# S4 method for antsImage
dim(x)
# S4 method for antsImage
min(x)
# S4 method for antsImage
max(x)
# S4 method for antsImage
var(x)
# S4 method for antsImage
sd(x)
# S4 method for antsImage
is.na(x)
# S4 method for antsImage
as.numeric(x, mask = logical(),
  region = new("antsRegion", index = integer(), size = integer()))
# S4 method for antsImage
as.matrix(x, mask = logical(),
  region = new("antsRegion", index = integer(), size = integer()))
# S4 method for antsImage
as.array(x, mask = logical(),
  region = new("antsRegion", index = integer(), size = integer()))
# S4 method for antsImage,ANY
==(e1, e2)
# S4 method for antsImage,ANY
!=(e1, e2)
# S4 method for antsImage,ANY
<=(e1, e2)
# S4 method for antsImage,ANY
>=(e1, e2)
# S4 method for antsImage,ANY
<(e1, e2)
