- 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)
