		1669	=head2 ALPHA CHANNEL SUPPORT
		1670
		1671	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1672	their act together, rxvt-unicode will do its own alpha channel management:
		1673
		1674	You can prefix any colour with an opaqueness percentage enclosed in
		1675	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1676	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1677	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1678	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1679	is the recommended format to specify transparency values, and works with
		1680	all ways to specify a colour.
		1681
		1682	For complete control, rxvt-unicode also supports
		1683	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1684	specifications, where the additional C<aaaa> component specifies opacity
		1685	(alpha) values. The minimum value of C<0000> is completely transparent,
		1686	while C<ffff> is completely opaque). The two example colours from
		1687	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1688	C<rgba:0000/ff00/0000/f332>.
		1689
		1690	You probably need to specify B<"-depth 32">, too, to force a visual with
		1691	alpha channels, and have the luck that your X-server uses ARGB pixel
		1692	layout, as X is far from just supporting ARGB visuals out of the box, and
		1693	rxvt-unicode just fudges around.
		1694
		1695	For example, the following selects an almost completely transparent black
		1696	background, and an almost opaque pink foreground:
		1697
		1698	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1699
		1700	When not using a background image, then the interpretation of the
		1701	alpha channel is up to your compositing manager (most interpret it as
		1702	transparency of course).
		1703
		1704	When using a background pixmap or pseudo-transparency, then the background
		1705	colour will always behave as if it were completely transparent (so the
		1706	background image shows instead), regardless of how it was specified, while
		1707	other colours will either be transparent as specified (the background
		1708	image will show through) on servers supporting the RENDER extension, or
		1709	fully opaque on servers not supporting the RENDER EXTENSION.
		1710
		1711	Please note that due to bugs in Xft, specifying alpha values might result
		1712	in garbage being displayed when the X-server does not support the RENDER
		1713	extension.
