NAME
       Gtk2::ImageView::Zoom -	Functions for dealing with zoom factors

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

METHODS
   double = Gtk2::ImageView::Zoom->clamp_zoom ($zoom)
       o   $zoom (double)

       Returns the zoom factor clamped to the minumum and maximum allowed values.

   double = Gtk2::ImageView::Zoom->get_max_zoom
       Returns the maximum allowed zoom factor.

   double = Gtk2::ImageView::Zoom->get_min_zoom
       Returns the minimum allowed zoom factor.

   double = Gtk2::ImageView::Zoom->get_zoom_in ($zoom)
       o   $zoom (double)

       Returns the zoom factor that is one step larger than the supplied zoom factor.

   double = Gtk2::ImageView::Zoom->get_zoom_out ($zoom)
       o   $zoom (double)

       Returns the zoom factor that is one step smaller than the supplied zoom factor.
