Gtk2::Gdk::Colormap 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". Glib::Object +----Gtk2::Gdk::Colormap

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

boolean = $colormap->alloc_color ($color, $writeable, $best_match)

list = $colormap->alloc_colors ($writeable, $best_match, ...)
Returns a list of boolean values, telling whether the color at the corresponding spot in ... could be allocated.

$colormap->free_colors (...)

color = $colormap->query_color ($pixel)

$colormap->rgb_find_color ($color)

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

colormap = Gtk2::Gdk::Colormap->get_system

visual = $colormap->get_visual
