Another Exercise- Clear the Blue Values What if you want to clear the blue from a picture? Set all the blue values to 0 for all the pixels The algorithm is similar to decreaseRed() and increaseRed() except You don’t need to get the value out for blue and multiply it by some value and then set the blue value Just set the blue value to 0 Georgia Institute of Technology

Georgia Institute of Technology Clear Blue Exercise In Picture.java Write the method public void clearBlue() That sets the blue value to 0 for all pixels in a picture Test with: String fileName = “c:/intro-prog-java/mediasources/caterpillar.jpg”; Picture p = new Picture(fileName); p.explore(); p.clearBlue(); When you clear the blue the white in the picture will look yellow.
