		1547	=head2 ALPHA CHANNEL SUPPORT
		1548
		1549	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1550	their act together, rxvt-unicode will do its own alpha channel management:
		1551
		1552	You can prefix any colour with an opaqueness percentage enclosed in
		1553	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1554	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1555	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1556	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1557	is the recommended format to specify transparency values, and works with
		1558	all ways to specify a colour.
		1559
		1560	For complete control, rxvt-unicode also supports
		1561	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1562	specifications, where the additional C<aaaa> component specifies opacity
		1563	(alpha) values. The minimum value of C<0000> is completely transparent,
		1564	while C<ffff> is completely opaque). The two example colours from
		1565	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1566	C<rgba:0000/ff00/0000/f332>.
		1567
		1568	You probably need to specify B<"-depth 32">, too, to force a visual with
		1569	alpha channels, and have the luck that your X-server uses ARGB pixel
		1570	layout, as X is far from just supporting ARGB visuals out of the box, and
		1571	rxvt-unicode just fudges around.
		1572
		1573	For example, the following selects an almost completely transparent black
		1574	background, and an almost opaque pink foreground:
		1575
		1576	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1577
		1578	When not using a background image, then the interpretation of the
		1579	alpha channel is up to your compositing manager (most interpret it as
		1580	transparency of course).
		1581
		1582	When using a background pixmap or pseudo-transparency, then the background
		1583	colour will always behave as if it were completely transparent (so the
		1584	background image shows instead), regardless of how it was specified, while
		1585	other colours will either be transparent as specified (the background
		1586	image will show through) on servers supporting the RENDER extension, or
		1587	fully opaque on servers not supporting the RENDER EXTENSION.
		1588
		1589	Please note that due to bugs in Xft, specifying alpha values might result
		1590	in garbage being displayed when the X-server does not support the RENDER
		1591	extension.
