1495
1496If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1497their act together, rxvt-unicode will do it's own alpha channel management:
1498
1499You can prefix any color with an opaquenes percentage enclosed in
1500brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1501(0-100) that specifies the opacity of the color, where C<0> is completely
1502transparent and C<100> is completely opaque. For example, C<[50]red> is a
1503half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1504is the recommended format to specify transparency values, and works with
1505all ways to specify a colour.
1506
1507For complete control, rxvt-unicode also supports
1508C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1509specifications, where the additional C<aaaa> component specifies opacity
1510(alpha) values. The minimum value of C<0000> is completely transparent,
1511while C<ffff> is completely opaque). The two example colours from
1512earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1513C<rgba:0000/ff00/0000/f332>.
1514
1515You probably need to specify B<"-depth 32">, too, to force a visual with
1516alpha channels, and have the luck that your X-server uses ARGB pixel
1517layout, as X is far from just supporting ARGB visuals out of the box, and
1518rxvt-unicode just fudges around.
1519
1520For example, the following selects an almost completely transparent black
1521background, and an almost opaque pink foreground:
1522
1523 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1524
1525When not using a background image, then the interpretation of the
1526alpha channel is up to your compositing manager (most interpret it as
1527transparency of course).
1528
1529When using a background pixmap or pseudo-transparency, then the background
1530colour will always behave as if it were completely transparent (so the
1531background image shows instead), regardless of how it was specified, while
1532other colours will either be transparent as specified (the background
1533image will show through) on servers supporting the RENDER extension, or
1534fully opaque on servers not supporting the RENDER EXTENSION.
1535
1536Please note that due to bugs in Xft, specifying alpha values might result
1537in garbage being displayed when the X-server does not support the RENDER
1538extension.
