Mask Editor Menu
The Mask Editor menu contains the selections used to edit previously
generated or stored masks using the automask menu. By using the mask
editor menu, it is also possible to clear any existing masks and create a new
one using the mark and connect-point method.
If the active limit mask (defined by the limit mask softkey) is not displayed,
pressing any softkey in the mask editor menu (except clear mask or main
mask menu) causes the active limit mask to display.
Mark Point Softkey
The mark point softkey records the current horizontal and vertical field
values. This point is used as the anchor point when connecting or clearing
points from the screen. These values are displayed in the horiz-vert softkey,
and represented on the screen at the junction of the x2/y2 markers. When
the softkey is pressed, the current values are saved, and the xl/yl markers
are moved to that point on the screen (imposed over the x2/y2 markers).
Connect Points Softkey
The connect points softkey replaces the portion of the existing active
limit mask from the mark point (junction of x1/yl markers) to the connect
point (junction of x2/y2 markers) with a straight line.
Clear Points Softkey
The clear points softkey replaces the portion of the existing active limit
mask from the mark point (junction of xl/y1 markers) to the connecting
point (junction of x2/y2 markers) with a hole.
