The image of an original may be shifted as fol-
lows by combining shifts in main and sub scan-
ning directions.
q Corner Shift
The coordinates (X1, Y1) of the corner of a
specific area is moved to any of the four cor-
ners of the copy.
w Center Shift
The coordinates (Xm, Ym) are computed from
the size of the area to be shifted and the size
of the copy so that the margins at the top and
bottom and left and right will be identical; the
area will be moved to X1 and Y1.
