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.

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
