Gtk2::Gdk::Colormap \- wrapper for GdkColormap
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Colormaps are used to store the mappings between the \s-1RGB\s0 values you ask for
and the actual, hardware-dependent values used to display those colors.
The \f(CW\*(C`$colormap\->alloc_color\*(C'\fR and \f(CW\*(C`$colormap\->alloc_colors\*(C'\fR 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
\&\f(CW\*(C`$colormap\->free_colors\*(C'\fR to release those spots in the colormap
allocated by \f(CW\*(C`alloc_color\*(C'\fR and \f(CW\*(C`alloc_colors\*(C'\fR.
