Gtk2::Gdk::Colormap3pm

Wrapper for gdkcolormap

Overview

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, $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.

$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
