1502
1503If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1504their act together, rxvt-unicode will do it's own alpha channel management:
1505
1506You can prefix any color with an opaquenes percentage enclosed in
1507brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1508(0-100) that specifies the opacity of the color, where C<0> is completely
1509transparent and C<100> is completely opaque. For example, C<[50]red> is a
1510half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1511is the recommended format to specify transparency values, and works with
1512all ways to specify a colour.
1513
1514For complete control, rxvt-unicode also supports
1515C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1516specifications, where the additional C<aaaa> component specifies opacity
1517(alpha) values. The minimum value of C<0000> is completely transparent,
1518while C<ffff> is completely opaque). The two example colours from
1519earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1520C<rgba:0000/ff00/0000/f332>.
1521
1522You probably need to specify B<"-depth 32">, too, to force a visual with
1523alpha channels, and have the luck that your X-server uses ARGB pixel
1524layout, as X is far from just supporting ARGB visuals out of the box, and
1525rxvt-unicode just fudges around.
1526
1527For example, the following selects an almost completely transparent black
1528background, and an almost opaque pink foreground:
1529
1530 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1531
1532When not using a background image, then the interpretation of the
1533alpha channel is up to your compositing manager (most interpret it as
1534transparency of course).
1535
1536When using a background pixmap or pseudo-transparency, then the background
1537colour will always behave as if it were completely transparent (so the
1538background image shows instead), regardless of how it was specified, while
1539other colours will either be transparent as specified (the background
1540image will show through) on servers supporting the RENDER extension, or
1541fully opaque on servers not supporting the RENDER EXTENSION.
1542
1543Please note that due to bugs in Xft, specifying alpha values might result
1544in garbage being displayed when the X-server does not support the RENDER
1545extension.
