1484=head2 ALPHA CHANNEL SUPPORT
1485
1486If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1487their act together, rxvt-unicode will do it's own alpha channel management:
1488
1489You can prefix any color with an opaquenes percentage enclosed in
1490brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1491(0-100) that specifies the opacity of the color, where C<0> is completely
1492transparent and C<100> is completely opaque. For example, C<[50]red> is a
1493half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1494is the recommended format to specify transparency values, and works with
1495all ways to specify a colour.
1496
1497For complete control, rxvt-unicode also supports
1498C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1499specifications, where the additional C<aaaa> component specifies opacity
1500(alpha) values. The minimum value of C<0000> is completely transparent,
1501while C<ffff> is completely opaque). The two example colours from
1502earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1503C<rgba:0000/ff00/0000/f332>.
1504
1505You probably need to specify B<"-depth 32">, too, to force a visual with
1506alpha channels, and have the luck that your X-server uses ARGB pixel
1507layout, as X is far from just supporting ARGB visuals out of the box, and
1508rxvt-unicode just fudges around.
1509
1510For example, the following selects an almost completely transparent black
1511background, and an almost opaque pink foreground:
1512
1513 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1514
1515When not using a background image, then the interpretation of the
1516alpha channel is up to your compositing manager (most interpret it as
1517transparency of course).
1518
1519When using a background pixmap or pseudo-transparency, then the background
1520colour will always behave as if it were completely transparent (so the
1521background image shows instead), regardless of how it was specified, while
1522other colours will either be transparent as specified (the background
1523image will show through) on servers supporting the RENDER extension, or
1524fully opaque on servers not supporting the RENDER EXTENSION.
1525
1526Please note that due to bugs in Xft, specifying alpha values might result
1527in garbage being displayed when the X-server does not support the RENDER
1528extension.
