Gtk2::Gdk::Colormap(3) User Contributed Perl Documentation Gtk2::Gdk::Colormap(3)NAMEGtk2::Gdk::ColormapDESCRIPTIONColormaps 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 "$colormap->free_colors" to release those spots in the colormap allocated by "alloc_color" and "alloc_colors".HIERARCHYGlib::Object +----Gtk2::Gdk::ColormapMETHODScolormap = Gtk2::Gdk::Colormap->new ($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 ...
