Manual Reference Pages - FACE (7)
face - face files
/lib/face contain a hierarchy of images of people.
In those directories are subdirectories named by the sizes of
the corresponding image files:
48x48x1 (48 by 48 pixels, one bit per pixel);
48x48x2 (48 by 48 pixels, two (grey) bits per pixel);
48x48x4 (48 by 48 pixels, four (grey) bits per pixel);
48x48x8 (48 by 48 pixels, eight (color-mapped) bits per pixel);
512x512x8 (512 by 512 pixels, eight (color-mapped) bits per pixel);
512x512x24 (512 by 512 pixels, twenty-four bits per pixel (3 times 8 bits
The large files serve no special purpose; they are stored
The small files are the icons displayed by
seemail (see Plan 9s
for depths less than 4, their format is special.
One- and two-bit deep icons are stored as text, one line of the file to one scan line
Each line is divided into 8-bit, 16-bit, or 32-bit big-endian words,
stored as a list of comma-separated hexadecimal C constants,
maps any of the machines in Bell Labs Research into the
astro, which then appears as a domain name in the
0x9200, 0x1bb0, 0x003e,
This odd format is historical and the programs that read it
are somewhat forgiving about blanks and the need for commas.
lib/face/*/.dict hold a correspondence between users at machines
and face files.
The format is
machine is the domain name of the machine sending the message,
user the name of the user sending it.
directory is a further subdirectory of (say)
/lib/face/48x48x1, named by a single letter corresponding to the first character
of the user names. The
file is the name of the file, typically but not always the user name,
ver is a number to distinguish different images, for example to
distinguish the image for Bill Gates from the image for Bill Joy,
both of which might otherwise be called
b/bill. For example, Bill Gates might be represented by the line
If multiple entries exist for a user in the various
faces chooses the highest pixel size less than or equal to that of the
display on which it is running.
Finally, or rather firstly, the file
/lib/face/.machinelist contains a list of machine/domain pairs, one per line,
to map any of a set of machines to a single domain name to
be looked up in the
.dict files. The machine name may be a regular expression,
so for example the entry
