NAME

       Gtk2::Gdk::Colormap

DESCRIPTION

       Colormaps are used to store the mappings between the RGB values you ask for and the actual, hardware-dependent values used to display those
       colors.	The "$colormap->alloc_color" and "$colormap->alloc_colors" methods do the necessary work to allocate a color within the visual;
       this actually has nothing to do with memory management, so it is important that you call "$colormap->free_colors" to release those spots in
       the colormap allocated by "alloc_color" and "alloc_colors".

METHODS

   colormap = Gtk2::Gdk::Colormap->new ($visual, $allocate)
       o   $visual (Gtk2::Gdk::Visual)

       o   $allocate (boolean)

   boolean = $colormap->alloc_color ($color, $writeable, $best_match)
       o   $color (Gtk2::Gdk::Color)

       o   $writeable (boolean)

       o   $best_match (boolean)

   list = $colormap->alloc_colors ($writeable, $best_match, ...)
       o   $writeable (boolean)

       o   $best_match (boolean)

       o   ... (list) of Gtk2::Gdk::Color's to be allocated

       Returns a list of boolean values, telling whether the color at the corresponding spot in ... could be allocated.

   $colormap->free_colors (...)
       o   ... (list) of Gtk2::Gdk::Color's to be freed

   color = $colormap->query_color ($pixel)
       o   $pixel (unsigned)

   $colormap->rgb_find_color ($color)
       o   $color (Gtk2::Gdk::Color)

   screen = $cmap->get_screen
       Since: gtk+ 2.2

   colormap = Gtk2::Gdk::Colormap->get_system
   visual = $colormap->get_visual
