Exploring MacPaint 165
The
Drawing Tools
THE DRAWING SURFACE
The
MacPaint
drawing surface
is
a portion
of
an
entire
page measuring 8 x
10
inches.
The
surface
is
composed
of
several thousand square segments
(or
pixels) which
are
selec-
tively turned black
or
allowed
to
remain white
to
create the
image.
The
drawing surface measures 416 x 240 pixels for a
total
of
99,840.
Due
to
this large
number
of
dots, each one
blends in with its neighbors to give the impression
of
a contin-
uous image.
The
entire page contains 720 x 576 points totalling
414,720 altogether.
The
printer will print each pixel in
an
area
of
.00019 square inches.
THE PENCIL
There are five drawing tools available with MacPaint:
• The pencil
• The paint brush
• The spray can
• The paint can
• The eraser
The
pencil
is
used
to
draw
lines
on
the drawing surface. To
illustrate the different tools,
leCs
draw
the picture shown in
figure 6.2.
After following these instructions, the Mac
operator
should begin
to
understand Mac
Paint
operation
and
should be
able
to
draw
a reasonable facsimile
of
the drawing. Let's begin
by drawing the tree trunk.
Use the mouse
to
insure
that
the
pencil symbol
is
selected by clicking it. Now move
the
pointer
onto
the drawing surface where it
is
transformed into a pencil.
Lines will
appear
at
the tip
of
the pencil as it
is
clicked
and
dragged.
Draw
the tree
trunk
as shown in figure 6.2.
If
your
rendition
is
unacceptable, read
ahead
to
the section
on
the
eraser
and
change it,
or
leave it for now. Your drawing might
resemble
that
shown in figure 6.3.
