Finishing with Mr. Quimby

• Last time we
• Figured out how to mirror over the books in bands
  (including writing a nice helper method to
  eliminate duplicate code. Good job!)

What can I do when things arent the size I want?

• Scaling Down My camera takes photos at 2304 x
  1708 pixels. That is WAY too big for posting to
  my website (where 300 x 200 would still be a good
  sized picture).

Scaling Down a Picture

• passionFlower.jpg is 640pixels wide and 480
  pixels high
• If we copy every other pixel we will have a new
  picture with width (640 / 2 320) and height
  (480 / 2 240)
