Key Modifiers

Edge modifiers

You can apply borders and other modifiers to the edge of
the key image.

Edge type and key fill/key source position

The key edge modification function has two modes: a
mode (key drop on mode) in which the key fill/key source
position moves downward, and a mode (key drop off
mode) in which it does not move.

Key drop on mode:

The key fill/key source position

moves downward by eight scan lines or four scan lines.
When a drop border or shadow is selected, it is
possible to apply a border to the top edge of the key.

Key drop off mode:

The key fill/key source position does

not move. When a drop border or shadow is selected,
it is not possible to apply a border to the top edge of the
key.

In key drop on mode, a menu setting selects between the
mode (4H mode) in which the key fill/key source position
is lowered by four scan lines, and the mode (8H mode) in
which the key fill/key source position is lowered by eight
scan lines.
When Fine Key is enabled, the edge width is forced into
the range 0.00 to 4.00.

In the following situations, the key drop on mode is
forcibly enabled.
• When the edge type is border, outline, or emboss
• When fine key is enabled

To fix key fill/key source to key drop off mode

Enable frame delay mode.
