Let's begin
our
discussion
of
Brush Mirrors by erasing the
last drawing
we
created
and
selecting Brush Mirrors. The
crossed lines indicate the axes
about
which the drawing will be
created.
To
select one, a few,
or
all axes for drawing, place the
pointer on the line representing the desired axis and click. The
selected line will thicken.
To
remove the Brush Mirrors option,
choose None from the Brush Mirrors window or unselect all
axes from the window and select
OK.
The vertical axis represents
an
imaginary vertical line
drawn down the center
of
the drawing surface. Any figure
drawn with the paint brush
on
one side
of
this line will be
duplicated in a mirror image on the
other
side as shown in
figure
6.29a. With the horizontal axis selected, figure 6.29b
shows
that
any drawing created in the upper portion of the
drawing surface will likewise be mirrored
on
the bottom part
of
the surface. The diagonal axes operate the same as the horizon-
tal and vertical. Picture
an
imaginary diagonal line appearing
at
45
degrees through the center of the drawing surface. Since
the drawing surface
is
rectangular and
not
square, the diagonal
will not extend from corner
to
corner on the surface. Because
of this, there is a region
on
the drawing surface
on
which there
is no corresponding mirroring area across the diagonal. Figure
6.29c shows this effect. Figure
6.29d shows the artistic poten-
tial of using all mirrors
at
once.
The next two options in the Goodies menu are informa-
tional in nature. The first, Introduction,
is
a quick reference
guide to the basic operation
of
MacPaint. The window is
repeated in figure 6.30.
