		1536	=head2 ALPHA CHANNEL SUPPORT
		1537
		1538	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1539	their act together, rxvt-unicode will do it's own alpha channel management:
		1540
		1541	You can prefix any colour with an opaqueness percentage enclosed in
		1542	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1543	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1544	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1545	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1546	is the recommended format to specify transparency values, and works with
		1547	all ways to specify a colour.
		1548
		1549	For complete control, rxvt-unicode also supports
		1550	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1551	specifications, where the additional C<aaaa> component specifies opacity
		1552	(alpha) values. The minimum value of C<0000> is completely transparent,
		1553	while C<ffff> is completely opaque). The two example colours from
		1554	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1555	C<rgba:0000/ff00/0000/f332>.
		1556
		1557	You probably need to specify B<"-depth 32">, too, to force a visual with
		1558	alpha channels, and have the luck that your X-server uses ARGB pixel
		1559	layout, as X is far from just supporting ARGB visuals out of the box, and
		1560	rxvt-unicode just fudges around.
		1561
		1562	For example, the following selects an almost completely transparent black
		1563	background, and an almost opaque pink foreground:
		1564
		1565	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1566
		1567	When not using a background image, then the interpretation of the
		1568	alpha channel is up to your compositing manager (most interpret it as
		1569	transparency of course).
		1570
		1571	When using a background pixmap or pseudo-transparency, then the background
		1572	colour will always behave as if it were completely transparent (so the
		1573	background image shows instead), regardless of how it was specified, while
		1574	other colours will either be transparent as specified (the background
		1575	image will show through) on servers supporting the RENDER extension, or
		1576	fully opaque on servers not supporting the RENDER EXTENSION.
		1577
		1578	Please note that due to bugs in Xft, specifying alpha values might result
		1579	in garbage being displayed when the X-server does not support the RENDER
		1580	extension.
