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)

       ·   $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)

       ·   $zoom (double)

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

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

       ·   $zoom (double)

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