3.8.3. Controlling the Ellipse Attributes
When the
ellipse
object is selected the
CTRL SEL
button is used to select which of its attributes (colour.
line width, position, size, or individual axes of the
ellipse
) will be adjusted by turning the shaft encoder
knobs. Press the
CTRL SEL
button until the desired
CTRL SEL
item is shown on the front panel. When
you have chosen the desired
CTRL SEL
item press the
ELLIPSE
button again or turn one of the shaft
encoder knobs to begin controlling the selected attribute of the
ellipse
. The selected attribute for control
will show on the
ctrl
line of the OSD.
The items that will be shown in the
ellipse
CTRL SEL
menu depend on the
MODE
settings and the
settings in the
SETUP
menu. In the sections describing the
CTRL SEL
items, the relevant settings from
the
ellipse
MODE
and
SETUP
menus are shown where necessary.

Controlling the Ellipse Colour
Colour
The colour of the
ellipse
object can be adjusted in the range of “0” through “14”, in single digit
increments, using either shaft encoder. The colours that will be displayed for each value are
shown in Table 3-2.

Line Width
The line width of the
ellipse
object can be adjusted in the range of “3” through “11”, in
increments of two, using either shaft encoder. Only the pixels (lines) in the centre of the line
width are keyed at 100%. The edges of the line are keyed at a reduced level to reduce
aliasing.
