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.
