3.5.5 User defined settings
It is possible to set the scaling values and AFD output codes of four settings named
“User
scaling ” 1 to 4. The scaling values control horizontal and vertical zoom, and horizontal and
vertical center 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 center offset values are slightly more complicated as the calculation
depends on whether the active scaling zoom is greater of less than one.
Zoom of one or less:
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.
Zoom greater than 1:
The setting is in lines (vertical offset) and pixels (horizontal offset) but the values are also
scaled by the zoom factor. A zoom value larger than 1 with a position value of P will result in
the picture moving (P x zoom) pixels or lines.
