Centring The Mask On The Raster; Controlling The Mask Attributes; Controlling The Mask White Level; Controlling The Mask Size (Mask Centred, Aspect Ratio Off) - evertz 9590 Instruction Manual

The user is still able to adjust the size of the mask all the way out to the production aperture regardless of
the Mask Apert setting.

3.5.2.2. Centring the Mask on the Raster

Centre: H + V
This item is used to control whether the mask object is centred on the raster or not. The centre item is
only available when the SETUP menu item force centre is set to off.
Select H + V to force the mask object to be centred on the raster.
Select off to allow the mask object to be moved off centre. In this MODE it is possible to independently
position the top, bottom, left and right limits of the mask, or to size the whole mask, depending on the
settings of the aspect ratio MODE item and what CTRL SEL item is chosen.

3.5.3. Controlling the Mask Attributes

When the mask object is selected the CTRL SEL button is used to select which of its attributes (white
level, position, size, or individual edges of the object) 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 MASK button again or turn one of the shaft encoder knobs
to begin controlling the selected attribute of the mask.
The items that are shown in the mask 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 mask
MODE and SETUP menus are shown where necessary.

3.5.3.1. Controlling the Mask White Level

Level The white level can be adjusted in the range of "0" through "14", in single digit increments,
using either shaft encoder with "0" corresponding to "black" and "14" corresponding to "white".
