IMSCAN(1) (arend) IMSCAN(1)
NAME
imscan - scan greyscale images
SYNOPSIS
imscan [ -sN ] [ -lN ] file
DESCRIPTION
Imscan digitizes an image with an Imagitex grey-scale scan-
ner and places the result in the named file in the form of
picfile(5). The options are
-sN Set a scale factor 1≦N≦9, default 4. With scale factor
N the image is subsampled: only 1 out of every N×N pix-
els is stored. A larger scale factor, therefore, pro-
duces a smaller image.
-lN Use lens focal length N, where 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.

BUGS
It is hard to get more than 2000 pixels per scanline reli-
ably. For large originals, higher scale factors work better
than smaller ones.
