Gtk2::Gdk::Colormap(3)User Contributed Perl DocumentatioGtk2::Gdk::Colormap(3)NAMEGtk2::Gdk::ColormapDESCRIPTION
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, $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
