[solved]-Write Program Three Functions Sepia Removeallred Grayscale Sepia Tone Images Brownish Col Q38998291
Write a program that has three functions: sepia(),remove_all_red(), and gray_scale().
Sepia Tone images are those brownish colored images that mayremind you of times past. The formula for creating a sepia tone isas 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)
where R, G, and B are the original image pixel red, green andblue values.
Hint: Remember thatRGB 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()
We are using Python 3. PyCharm.
