Handbook
Erasing a section by erasing a portion, then releasing the
mouse,
and
then erasing the rest would make the first
part
of
the erasure irreversible. This applies
to
all actions taken with
MacPaint.
Lines and Shapes
Now
that
we
have discussed the rudimentary techniques
of
drawing
and
erasing,
and
have witnessed the versatility
of
alternately doing, undoing,
and
redoing
an
action,
we
can
move
on
to more complex shapes.
THE LINE
Notice the line symbol to the left
of
the eraser. This feature
allows the
operator
to
draw
a straight line between any two
points.
To help provide a reference basis for
our
drawing, use the
paint
brush to create the outline
of
the hill. Since the paint
brush will paint over the tree, you will need to break up the line.
Now
draw
the kite string as shown in figure 6.2. Select the line,
and
place the cross hairs
at
the line's beginning point.
Drag
the
line
to
the point in the sky where the kite
is
positioned. Notice
that
the line originates
at
the point where the mouse
button
was
pressed and extends to the cross hairs until the
button
is
released. Since the line
is
now in recent memory, you can
undo
it if it
is
incorrect. The latest version now appears in figure
6.
