4. The following program loads and displays an image. Complete the modify function to change the brightness of the image. The parameter m is a multiplication factor. modify will will multiply each pixel by m - that means you need to multiply the red, green, and blue channels by m, create a new pixel with new red, green, and blue values, and replace the old pixel with the new pixel. Be sure none of the red, green, and blue values exceed 255 (if a value is greater than 255, set it to 255). Your program should work for images of any size. A good example is the sepia tone exercise. Do not change the main function, except to try different values for the multiplication factor.
