+.SH NAME
+imscan \(mi scan greyscale images
+.SH SYNOPSIS
+.B imscan
+[
+.BI -s N
+]
+[
+.BI -l N
+]
+.I file
+.SH DESCRIPTION
+.I Imscan
+digitizes an image with an Imagitex grey-scale scanner
+and places the result in the named file in the form of
+.IR picfile (5).
+The options are
+.TP
+.BI -s N
+Set a scale factor 
+.RI 1\(<= N \(<=9,
+default 4.
+With scale factor
+.I N
+the image is subsampled: only 1 out of every
+.I N\(muN
+pixels is stored. 
+A larger scale factor, therefore, produces a smaller image.
+.TP
+.BI -l N
+Use lens focal length
+.I N,
+where
+.I N
+is either 5 or 8 (default).
+The 8-inch lens scans images at 480 dots per inch.
+The 5-inch lens scans at 754 dots per inch.

+.IR cscan (1),
+.IR pico (1),
+.IR qsnap (1),
+.I mugs
+in
+.IR face (9.7),
+.IR picfile (5)
+.SH BUGS
+It is hard to get more than 2000 pixels per scanline reliably.
+For large originals, higher scale factors work better than 
+smaller ones.
