Tips
 
 This
week’s
homework
assignment
is
supposed
to
be
FUN.
But
there
are
a
few
tips
to
help
you
either
get
 started
or
to
keep
you
moving
along.
 
 1. Load
your
picture
of
you
and
your
partner
in
solid
colored
t‐shirts
in
front
of
the
bright
green
 sheet
into
Dr.
Java
and
use
the
explore()
method
on
it
to
see
what
levels
of
red,
green
and
blue
are
 in
the
green
sheet
that
are
not
in
your
skin
or
hair
or
clothes.
This
will
help
you
to
determine
your
 threshold
for
the
colors
so
that
you
can
make
your
green
screen
effect
as
best
as
possible.
(Explore
 your
shirts
too
so
that
you
can
make
sure
these
are
as
clean
as
possible).
 
 2. When
you
are
taking
your
picture
BE
CREATIVE,
use
chairs
or
jump
up!
 
 3. DO
NOT
color
your
picture
based
on
location
(the
top
half
is
all
green
so
I’m
just
going
to
color
 while
y
<
pic.getHeight()/2
–
NO!)
You
MUST
use
COLOR
THRESHOLDS,
not
location
ones.
 
 4. If
your
skin
has
very
similar
RGB
values
to
the
green
sheet,
you
MAY
load
the
picture
into
Paint
 first
and
make
the
green
brighter,
but
you
MAY
NOT
color
in
the
green
in
Paint
with
your
new
 background.
The
picture
you
load
into
your
program
must
be
green
screen
with
solid
T’s.
 
 5. You
may
run
into
the
problem
that
your
new
background
has
blue
in
it
and
then
you
try
to
color
 your
blue
T‐Shirt
and
it
colors
also
the
new
background.
DO
NOT
fix
this
by
using
location
specific
 code,
think
of
more
creative
ways.
(i.e.
referencing
the
original
picture
but
coloring
the
new
one
–
 SHHHHH).
 
 6. You
may
run
into
the
problem
that
your
picture
is
bigger
then
the
new
background
you
want
to
 use
or
vice‐versa.
You
can
solve
this
in
a
few
ways.
One
is
you
are
allowed
to
re‐size
in
Paint
 beforehand,
but
this
may
still
be
an
issue
when
you
are
trying
to
copy
a
small
image
(100,100)
 onto
your
shirt
(located
starting
at
200,200
in
your
big
picture).
In
this
case,
you
need
to
keep
 track
of
two
different
indices
–
the
one
to
your
picture
and
the
one
to
the
shirt
picture.
(Same
goes
 for
background).
 
 7. Try
to
make
your
pictures
look
as
awesome
as
possible,
take
a
little
time
to
plan
out
the
picture
 first

 
 8. START
EARLY
and
get
into
the
lab
playing
with
this
ASAP.
Tutors
will
be
there
to
help,
but
it
 won’t
be
much
help
if
you
are
all
there
on
Monday
trying
to
get
help
when
you
had
most
of
the
 previous
week!
Also,
this
one
is
supposed
to
be
fun,
so
the
earlier
you
start,
the
more
fun
you
can
 have
with
it

 
 I
hope
these
few
tips
help
you
get
started
and
stay
started.
If
you
need
clarification
please
be
sure
to
see
a
 tutor!!
