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
