Fall 2007 Test 1 Review - Mangle

Post questions here.
is it b?
Nope. Thanks! Brittany Duncan
I think it's C.
I also think it is C.

def mangle(picture):
  for x in range(1,getWidth(picture)/2):
    for y in range(1,getHeight(picture)/2):
      setColor(getPixel(picture,x,y),white)
  for x in range(getWidth(picture)/2,getWidth(picture)):
    for y in range(getHeight(picture)/2,getHeight(picture)):
      setColor(getPixel(picture,x,y),black)


The "mangled" picture has a white square in the top left area and a black square in the bottom right area.

The first nested "for" loop starts from (1,1) and goes to (getWidth/2,getHeight/2) and creates a white quadrilateral. It's starting from the top left corner and ends at the midpoint of the picture.

The second nested "for" loop starts from (getWidth/2,getHeight/2) - the end point of the white quadrilateral - and goes to (getWidth,getHeight). It creates a black quadrilateral.
