  img = readImage(system.file("images", "sample-color.png", package="EBImage"))[257:768,,]
  x = resize(img, 128, 128)
  xt = list()
  for (t in seq(0.1, 5, len=9)) xt=c(xt, list(gblur(x, s=t)))
  xt = combine(xt)
  display(xt, title='Blurred images')

  ## tile
  xt = tile(xt, 3)
  display(xt, title='Tiles')

  ## untile
  xu = untile(img, c(3, 3))
