NAME

6       Gtk2::Gdk::Colormap
7

DESCRIPTION

9       Colormaps are used to store the mappings between the RGB values you ask
10       for and the actual, hardware-dependent values used to display those
11       colors.  The "$colormap->alloc_color" and "$colormap->alloc_colors"
12       methods do the necessary work to allocate a color within the visual;
13       this actually has nothing to do with memory management, so it is impor‐
14       tant that you call "$colormap->free_colors" to release those spots in
15       the colormap allocated by "alloc_color" and "alloc_colors".

METHODS

22       colormap = Gtk2::Gdk::Colormap->new ($visual, $allocate)
23
24           * $visual (Gtk2::Gdk::Visual)
25           * $allocate (boolean)
26
27       boolean = $colormap->alloc_color ($color, $writeable, $best_match)
28
29           * $color (Gtk2::Gdk::Color)
30           * $writeable (boolean)
31           * $best_match (boolean)
32
33       list = $colormap->alloc_colors ($writeable, $best_match, ...)
34
35           * $writeable (boolean)
36           * $best_match (boolean)
37           * ... (list) of Gtk2::Gdk::Color's to be allocated
38
39           Returns a list of boolean values, telling whether the color at the
40           corresponding spot in ... could be allocated.
41
42       $colormap->free_colors (...)
43
44           * ... (list) of Gtk2::Gdk::Color's to be freed
45
46       color = $colormap->query_color ($pixel)
47
48           * $pixel (unsigned)
49
50       $colormap->rgb_find_color ($color)
51
52           * $color (Gtk2::Gdk::Color)
53
54       screen = $cmap->get_screen
55
56       colormap = Gtk2::Gdk::Colormap->get_system

58       visual = $colormap->get_visual
