Gtk2::Gdk::Colormap(3p)

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
Since: gtk+ 2.2

  colormap = Gtk2::Gdk::Colormap->get_system

  visual = $colormap->get_visual
