Image

Given an image filename and ints a and b which are 1 or more, produce a new output image with three features: (1) a blank stripe 10 pixels high at the top; (2) a vertically flipped copy of the original image, with blank margins a pixels wide on both sides; and (3) a yellow stripe b pixels high across the bottom. Add code in the three indicated places.

1. Write one line of code to create the output image.
2. The code that copies the original image is provided. Write one line to set pixel_out inside the loop.
3. Write separate loops and other code to fill the yellow rectangle. You can make a white pixel yellow by setting its blue value to 0. Assume return out is the last line.

def do_image(filename, a, b):
    image = SimpleImage(filename)
    #### 1. Create "out" image


    # Write flipped image to out
    for y in range(image.height):
        for x in range(image.width):
            pixel = image.get_pixel(x, y)
            #### 2. Set "pixel_out"


            pixel_out.red = pixel.red
            pixel_out.green = pixel.green
            pixel_out.blue = pixel.blue

    #### 3. Fill yellow rectangle

def do_image(filename, a, b):
    image = SimpleImage(filename)
    out = SimpleImage.blank(image.width + 2 * a,
                            image.height + 10 + b)

    # Copy the image upside down, below the top stripe.
    for y in range(image.height):
        for x in range(image.width):
            pixel = image.get_pixel(x, y)
            pixel_out = out.get_pixel(
                a + x, 10 + image.height - 1 - y)
            pixel_out.red = pixel.red
            pixel_out.green = pixel.green
            pixel_out.blue = pixel.blue

    # Fill the bottom stripe yellow.
    for y in range(b):
        for x in range(out.width):
            pixel_yellow = out.get_pixel(
                x, 10 + image.height + y)
            pixel_yellow.blue = 0

    return out
