3.5.3 User defined settings
I
t is possible to set the scaling values and AFD codes of four settings named “User scaling”
1 to 4. The scaling values control horizontal and vertical, zoom and centre offset.
Vertical and horizontal zoom can be adjusted within the range 0.5 to 1.5. The values denote
the enlargement of the output image.
Vertical and horizontal centre offset or position values are slightly more complicated as the
calculation depends on whether the active scaling zoom is greater of less than one.
3.5.3.1 Pos when zoom is less than 1:
The setting is in lines (vertical offset) and pixels (horizontal offset). A position value of P will
result in the picture moving P pixels or lines.
