Procedure to define a mask
NNNNNNNNNNNNNNNNNNNNNNNNNNNNN
polygon # The Polygon # function allows you to select one of the eight polygons that
you
want
to
edit
or
create.
If
the
mask
does
not
have
a
polygon
with
the
selected
number
,
you
can
create that
polygon
using
the
Edit
P
olygon
menu.
If
a
polygon
is
scaled
o of
the
screen,
the
number
of
that
polygon
is
still
displayed on the screen. However
, it is possible that a polygon number can
obscure another polygon number
. Also
, if a polygon is scaled completely o
the screen, that polygon is not used in the mask test.
When editing a mask with

selections for each polygon: the standard mask (labeled \STD"), the
