Question

We use python.

Consider the following procedures for accessing and modifying the color channels of an RGB pixel.

RED (pixel): Extracts the red value from the color of pixel

GREEN (pixel): Extracts the green value from the color of pixel

BLUE (pixel): Extracts the blue value from the color of pixel

SETCOLOR (pixel,r,g,b): Replaces the red, green, and blue values of pixel with new values (r, g, and b, respectively)

Using the above procedures, a programmer has written the following code segment to modify image, an array representing the color values for each pixel within an RGB image.

FOR EACH pixel IN image { r = 255 - RED(pixel) g = 255 - GREEN(pixel) b = 255 - BLUE(pixel) SETCOLOR (pixel, r, g, b) }

Which of the following best describes the resulting image?

Multiple Choice:

A. The resulting image will be completely white.

B. All of the colors of the resulting image will be inverted, like a negative, of the original image.

C. The resulting image will be a grayscale version of the original image.

D. The overall brightness of all pixels in the resulting image will be darkened.
