Gtk2::Gdk::Colormap

NAME

Gtk2::Gdk::Colormap − wrapper for GdkColormap

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
