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
$colormap->free_colors to release those spots in the colormap
allocated by alloc_color and alloc_colors.
HIERARCHY
Glib::Object +----Gtk2::Gdk::Colormap
METHODS
colormap = Gtk2::Gdk::Colormap->new ($visual, $allocate)
- * $visual (Gtk2::Gdk::Visual)
- * $allocate (boolean)
boolean = $colormap->alloc_color ($color, $writeable, $best_match)
- * $color (Gtk2::Gdk::Color)
- * $writeable (boolean)
- * $best_match (boolean)
list = $colormap->alloc_colors ($writeable, $best_match, ...)
- * $writeable (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
