6. Sub Scan Resolution Conversion

Since the scanner always scans at 15.4 line/mm resolution, sub scan resolu-
tion has to be converted when transmitting to a terminal which is not capable
of higher resolutions.
Standard: The first and third lines in each four-line group are OR processed
for transmission. Other lines are deleted.
1st Line
2nd Line
3rd Line
4th Line
Detail: Pairs of lines are OR processed for transmission.

Fine resolution, alternate lines (even-numbered lines) are deleted before
transmission.
