display(x, no.GTK, main, colorize,
title = paste(deparse(substitute(x))),
useGTK = TRUE)
animate(x)
x |

By default (and if available), the display function uses GTK to
open a window and display the image. Multiple windows can be opened in
this way.
If GTK is not available or if useGTK is FALSE,
ImageMagick is used; only one window at a time can be open,
and it needs to be closed by the user interactively before
the next window can be opened. The ImageMagick display is not
available on MS-Windows.
The animate function shows an animated sequence of images and uses ImageMagick. Similar limitations as for display apply
(only one window, not on MS-Windows.)
The functions are called for their side effect.
Return value is invisible NULL.
