Frame Store Operations (Option)
Mask Store Option
The Mask Store function provides the ability to freeze and store
mask signals to use in building effects. This function requires
version 5.2 software and new Frame Store and Mask Store
hardware.
NOTE:
You may want to browse the descriptions below; then
experiment with the brush and screen selections provided on the Mask
Store Menu.
1. From the Mask Store Menu, select either BLACK SCREEN or
WHITE SCREEN for your Mask Store background. Then select
either a BLACK (for white screen) or WHITE (for black screen)
brush with the
BRUSH SOURCE
button. Hint: If you are using
a black brush on a white screen you may want to adjust the
BRUSH OPACITY
soft knob to a value of 20% or higher. A value
of 0 to 5% makes the brush strokes very hard to see.
2. Use the DRAW MODE button in the Mask Store Menu to select
either the STRAIGHT or FREEHAND draw mode.
STRAIGHT automatically draws a straight line between two
cursor points. To make the first point, press the pen onto the
tablet; then lift up slightly. Keeping the pen about a 1/2 inch
above the tablet, move the pen to where you want the straight
line to end. Press the pen down for the second point and to
complete the line. (A “temporary” line on the monitor
provides a visual cue as to where the line is going.)
After drawing a closed region, press SAVE. (In case FILL
SHAPE
fails to produce the desired results, you can revert to
the last saved image by pressing UNDO, touch up any “leaks,”
and try FILL SHAPE again.)
3. Use FILL SHAPE to fill a completely enclosed shape with either
black or white, as selected by
BRUSH SOURCE. If the shape is
not completely closed, the fill will “leak out” and fill the entire
screen. (This may happen if you have the BRUSH SOFTNESS
soft knob set to a high value.
