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 "$colormap->free_colors" to release those spots in the colormap allocated by "alloc_color" and "alloc_colors".
HIERARCHY¶
Glib::Object +----Gtk2::Gdk::Colormap
METHODS¶
colormap = Gtk2::Gdk::Colormap->new ($visual, $allocate)¶
- $visual (Gtk2::Gdk::Visual)
- $allocate (boolean)
boolean = $colormap->alloc_color ($color, $writable, $best_match)¶
- $color (Gtk2::Gdk::Color)
- $writable (boolean)
- $best_match (boolean)
list = $colormap->alloc_colors ($writable, $best_match, ...)¶
- $writable (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.

- •
- ... (list) of Gtk2::Gdk::Color's to be freed

- $pixel (unsigned)
$colormap->rgb_find_color ($color)¶
