Transparency Level
The transparency level controls the amount of background video, across the
whole picture that will 'seep' through the keyed image. This function is
achieved by attenuating the key signal.
Set Position
The Set Position sub menu offers a choice between horizontal and vertical.
Use the arrow keys W X to select between options as indicated by the
brackets enclosing that option. Press the enter key to apply the selection.
Images may be repositioned horizontally (left and right) and vertically (up
and down) in increments of two pixels. The settings, accessed through the set
position sub-menu, define the relative position between the top left corner of
the visible background and the top left corner of the image.
For a horizontal adjustment, the setting is the number of pixels that the image
is to the right of the top left visible corner of the screen. Negative values are
displayed if the image is moved to the left of that top corner reference where
part of the image would be outside of the visible screen area.
For a vertical adjustment, the setting is the number of pixels that the image is
below the top left visible corner of the screen. Negative values are displayed
if the image is moved above the top corner reference where part of the image
would be outside of the visible screen area.
Masking Images
Images may be masked by restricting the margins and confining an image to
less than full screen. Before any image can be masked the feature must be
turned to enabled. An option within the Set Masking sub menu provides the
enable/disable switching.
