Radio Shack TRS-80 X-PAD GT-116 - Page 25

Apply
steady pressure
—
keep pressure on the
Pen's tip
so
your
drawing
is contiguous.
Contiguous drawing
—
X-Pad
sets
points in a
contiguous
fashion. For example, draw
a
line in the
lower-left corner
of
X-Pad
and then draw one
in
the
upper-right
corner.
Use a
slow hand
—
If you
want
to
"shade"
(shading in
an area
by
moving
the Pen
over and
over the
area),
you'll have to
move the
Pen
slowly over the
area
to be
shaded.
You
must
also
keep
the
Pen
perpendicular so
the Pen's
signals
are
evenly
sent.
X-Pad-Oma!

Where the
Pen
Comes
Sweeping Down the Pad
To
get you started, we've
got
some
drawing ideas
for
you:
•
Write
your name
in
longhand,
looking
at
your
paper
as
you
move
the
Pen.
After
you've done
that,
try
it
again
by just looking
at
the Screen as
you
write your name
(pretty hard
to cross those t's and
dot those
i's).
•
Draw
a
four-leaf clover.
•
Draw
a
five-pointed
star.
•
Draw
a
big "dreamhouse" with
a garage,
driveway, and
smokestack
with
billowing smoke.
•
Take
a
map
or drawing from a magazine,
newspaper,
etc.,
place
it
on
the
Writing Surface and trace all or
part
of
it
with the X-Pad.
•
Draw
the
following
geometric figures by only
looking
at
the
paper (no cheating,
now!):
circle, triangle,
rectangle,
pentagon,
hexagon,
square, and octagon.
•
Draw
a
three-dimensional
box.
