Hi Pod,
Dean has illustrated the use of "shaded" in pic. You can get a list of
predefined colour names by looking for the file "ps.tmac". You can also
define your own colours (from 'info'):-
===========================================
-- Request: .defcolor ident scheme color_components
Define color with name IDENT. SCHEME can be one of the following
values: `rgb' (three components), `cmy' (three components), `cmyk'
(four components), and `gray' or `grey' (one component).
Color components can be given either as a hexadecimal string or as
positive decimal integers in the range 0-65535. A hexadecimal
string contains all color components concatenated. It must start
with either `#' or `##'; the former specifies hex values in the
range 0-255 (which are internally multiplied by 257), the latter
in the range 0-65535. Examples: `#FFC0CB' (pink), `##ffff0000ffff'
(magenta). The default color name value is device-specific
(usually black). It is possible that the default color for `\m'
and `\M' is not identical.
A new scaling indicator `f' has been introduced which multiplies
its value by 65536; this makes it convenient to specify color
components as fractions in the range 0 to 1 (1f equals 65536u).
Example:
.defcolor darkgreen rgb 0.1f 0.5f 0.2f
Note that `f' is the default scaling indicator for the `defcolor'
request, thus the above statement is equivalent to
.defcolor darkgreen rgb 0.1 0.5 0.2
==========================================
You must place your ".defcolor" BEFORE your .PS line. So, this should work:-
.defcolor GroovyGreen rgb #60b040
.defcolor PerfectPink rgb #f0b0b0
.PS
box height 0.3 shaded "GroovyGreen" "foofoo";
arrow arrowwid 1;
box width 3 height 3 shaded "PerfectPink";
{"foofoo" at last box .n + (0,-0.1);}
box width 1.8 height 1.5 at last box .w + (1.5,0);
.ps 8
{"\fBfoofoo()\fR" colour "GroovyGreen" at last box .n + (0,-0.3);}
.PE
Cheers
Deri
