		502
		503	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		504	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		505	quite a bit, so don't expect it to keep some specific state. It's best to
		506	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		507
		508	The window will not be destroyed when @@RXVT_NAME@@ exits.
		509
		510	It might be useful to know that @@RXVT_NAME@@ will not close file
		511	descriptors passed to it (except for stdin/out/err, of course), so you
		512	can use file descriptors to communicate with the programs within the
		513	terminal. This works regardless of whether the C<-embed> option was used or
		514	not.
		515
		516	Here is a short Gtk2-perl snippet that illustrates how this option can be
		517	used (a longer example is in F<doc/embed>):
		518
		519	my $rxvt = new Gtk2::Socket;
		520	$rxvt->signal_connect_after (realize => sub {
		521	my $xid = $_[0]->window->get_xid;

		523	});
		524
		525	=item B<-pty-fd> I<file descriptor>
		526
		527	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		528	pair but instead use the given file descriptor as the tty master. This is
		529	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		530	without having to run a program within it.
		531
		532	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		533	entries and will not tinker with pty/tty permissions - you have to do that
		534	yourself if you want that.
		535
		536	As an extremely special case, specifying C<-1> will completely suppress
		537	pty/tty operations, which is probably only useful in conjunction with some
		538	perl extension that manages the terminal.
		539
		540	Here is a example in perl that illustrates how this option can be used (a
		541	longer example is in F<doc/pty-fd>):
		542
		543	use IO::Pty;
		544	use Fcntl;
		545

		1521	=head2 ALPHA CHANNEL SUPPORT
		1522
		1523	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1524	their act together, rxvt-unicode will do it's own alpha channel management:
		1525
		1526	You can prefix any colour with an opaqueness percentage enclosed in
		1527	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1528	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1529	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1530	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1531	is the recommended format to specify transparency values, and works with
		1532	all ways to specify a colour.
		1533
		1534	For complete control, rxvt-unicode also supports
		1535	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1536	specifications, where the additional C<aaaa> component specifies opacity
		1537	(alpha) values. The minimum value of C<0000> is completely transparent,
		1538	while C<ffff> is completely opaque). The two example colours from
		1539	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1540	C<rgba:0000/ff00/0000/f332>.
		1541
		1542	You probably need to specify B<"-depth 32">, too, to force a visual with
		1543	alpha channels, and have the luck that your X-server uses ARGB pixel
		1544	layout, as X is far from just supporting ARGB visuals out of the box, and
		1545	rxvt-unicode just fudges around.
		1546
		1547	For example, the following selects an almost completely transparent black
		1548	background, and an almost opaque pink foreground:
		1549
		1550	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1551
		1552	When not using a background image, then the interpretation of the
		1553	alpha channel is up to your compositing manager (most interpret it as
		1554	transparency of course).
		1555
		1556	When using a background pixmap or pseudo-transparency, then the background
		1557	colour will always behave as if it were completely transparent (so the
		1558	background image shows instead), regardless of how it was specified, while
		1559	other colours will either be transparent as specified (the background
		1560	image will show through) on servers supporting the RENDER extension, or
		1561	fully opaque on servers not supporting the RENDER EXTENSION.
		1562
		1563	Please note that due to bugs in Xft, specifying alpha values might result
		1564	in garbage being displayed when the X-server does not support the RENDER
		1565	extension.
