NAME

6       Gtk2::ImageView::Zoom -  Functions for dealing with zoom factors
7

DESCRIPTION

9       GtkImageView uses a discrete amount of zoom factors for determining
10       which zoom to set. Using these functions, it is possible to retrieve
11       information and manipulate a zoom factor.
12
