The Grid option applies
to
all shapes except the irregular
curved shape (filled
or
open). In addition, it affects the selec-
tion rectangle, alpha-numerics, and the line. This allows the
artist to draw more accurately in graduated distances. Figure
6.22b
shows
an
example
of
graduated drawing using the irregu-
lar straight-sided shape. Each corner
of
the drawing
is
a grid
coordinate. Use the hand and eraser
to
make room and work
the example shown.
The standard drawing surface
is
sufficient for most draw-
ing needs. However, when outputting more detailed graphics,
the artist will require more exact control
of
the placement
of
each
dot
on the screen. The creators
of
Mac Paint designed the
FatBits option
to
satisfy this need. Much
of
our
example
diagram could have been created more easily if
we
had used
this option.
To use Fat Bits, simply select
that
option from the Goodies
menu. The area where the mouse
button
was last pressed will
expand
by a factor
of
64
to
cover the entire window. A copy
of
the figure
at
its original size will
appear
in a block in the
drawing surface's upper left-hand corner. Figure 6.23 shows
the FatBits version
of
the watermelon.
If
the mouse was not last
clicked
at
the figure to be magnified, use a non-drawing tool,
such as the hand,
to
click in the desired spot. Then select
FatBits.
Any tool
or
shape
can
be used within the FatBits
windo~.
The pencil can be used in a more versatile fashion within
that
window. The pencil was first described as a line drawing tool.
More accurately, it
is
a
dot
inversion tool. Normally, the pencil
draws a black line on a white background by inverting the dots
as it moves. When drawing
on
a black background, however,
the pencil creates a line by turning every
dot
in its path white.
As
such, the pencil acts as
both
a fine drawing and erasing tool.
In
fact, the pencil could be used in this manner to draw the line
through the watermelon. Notice
that
we
have done so in
our
examples.
You
can draw this line by using the pencil.
