Module 7 Grading Guideline

Note: If there is no file named PictureManipulator4.java submitted, 
award 0 points total for this assignment.

The testing of these submissions should be done by simply creating
an instance of the PictureManipulator4 in the Interactions pane and
then creating an instance of a Picture.  Pass the picture to the
appropriate methods and ensure results.  There should be a picture
object returned from the methods, so you can call show() on the
returned value to ensure the functionality of the methods.
		   
Point breakdown: (Partial credit only where indicated.)

[32 points] Sepia tint method
			(5) Method takes in parameter of Picture
			(5) Method creates a new picture that is the same size as
			    the original picture
			(5) Method needs to call grayscale method
			(5) Loop present to get pixels out of now grayscale picture
			(7) In loop, if statements used to change the colors for
			    the pixels accordingly
			(5) Returns a picture object has correct tints

[33 points] Copy all but white pixels method
			(5) Method takes in two parameters of type Picture, one to
			    take an image from and one to copy the image to (like in
				example, robot to the moon)
			(5) Loop present to get pixels out of original picture
			(4) In loop, for every pixel in the old picture, there is an
			    if-statement used to determine if the pixel is white.
			(7) If it is white, do not move pixel to other picture.
			(7) If it is not white, pixel should move to other image.
			(5) Returns the results of the copying

[35 points] Red, green, blue method
			(5) Method takes in parameter of Picture
			(5) Method creates a new picture that is the same size as 
			    original picture
			(5) Loop present to get pixels out of original picture
			(5) In loop, for every pixel in the old picture, the 
			    average color is computed
		    (5) If statement looks at value, and if less than 85, turns
			    turns the pixel green.
			(5) If less than 170, turns the pixel red.
			(5) Otherwise, turns the pixel blue.
			(5) Returns a picture object that only has red, green, and
