NAME

       Gtk2::Gdk::Colormap - wrapper for GdkColormap

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)
       •   $visual (Gtk2::Gdk::Visual)

       •   $allocate (boolean)

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

       •   $writable (boolean)

       •   $best_match (boolean)

   list = $colormap->alloc_colors ($writable, $best_match, ...)
       •   $writable (boolean)

       •   $best_match (boolean)

       •   ... (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 (...)
       •   ... (list) of Gtk2::Gdk::Color's to be freed

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

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

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

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