Description

1. Write a program that has three functions: sepia(), remove_all_red(), and gray_scale().Sepia Tone images are those brownish colored images that may remind you of times past. The formula for creating a sepia tone is as follows:

   newR = (R × 0.393 + G × 0.769 + B × 0.189)

   newG = (R × 0.349 + G × 0.686 + B × 0.168)

   newB = (R × 0.272 + G × 0.534 + B × 0.131)

   Red removal from an image:

   Simply set the R component to 0.

   Gray scale conversion:

   newR = (R × 0.289 + G × 0.587 + B × 0.114)

   newG = (R × 0.289 + G × 0.587 + B × 0.114)

   newB = (R × 0.289 + G × 0.587 + B × 0.114)

   Hint: Remember that rgb values must be integers between 0 and 255.

   You can get each pixel by using p = img.getPixel(col, row)

   Components of each pixel can be retrieved by p.getRed(), p.getGreen(), p.getBlue()

   #Starter code
   import image

   img = image.Image(“sample.jpg”)
   newimg = image.EmptyImage(img.getWidth(), img.getHeight())
   win = image.ImageWin()

   img.draw(win)
   win.exitonclick()
