CSCAN(1) (coma,pipe) CSCAN(1)
NAME
cscan - scan documents on canon scanner
SYNOPSIS
cscan [ option ... ] [ file ... ]
DESCRIPTION
Cscan acquires black-and-white images using the Canon 9030
Laser Copier flatbed document scanner located in the Graph-
ics Lab. Each file receives one image; multiple files are
scanned as fast as possible (every 12s, after a startup
delay). If no file is specified, one image is written to
the standard output.
Each image is compressed using the CCITT FAX Group 4 stan-
dard and supplied with a header as described in picfile(5).
The default page format is 3456 by 4400 pixels (i.e.
letter-size 8.64"×11.0" at 400 pixels/inch digitizing reso-
lution).
The options are:
-fx,y
Format is x by y pixels. X is truncated to a multiple
of 32.
-fL Double-letter format -f4416,6800 or 11"×17" at 400
pixels/inch (the largest possible).
-ss Sleep between scans for an extra s seconds.
-v Verbose: announce each file as it arrives.

BUGS
Although only 10s are required to acquire and compress each
image, it can take 40s for the first file to appear, due
largely to networking latencies involving rcp(1).
Cscan is unkillable: scanning continues and the files keep
coming.
The automatic document feeder is not supported.
The resolution recorded in the header is always 400
pixels/inch, even though it is possible manually to zoom to
other resolutions.
