1.      Complete the draw_lines() function to draw two lines on edinburgh-castle.gif: a green vertical line 1/3 of the way from the left edge, and a horizontal blue line 1/3 from the top. The vertical line should extend from the top of the image to the bottom; the horizontal line should extend from the left edge to the right edge. For full credit, use a loop and draw the lines pixel by pixel. The process is very similar to the lines we drew in class across the middle of an image.

2.      Complete the border() function to draw a black border 10 pixels wide around arch.gif. Don't make the image larger—draw the border over the top and bottom 10 rows, and the leftmost and rightmost 10 columns of the image. For full credit, draw the lines using loops and draw them pixel by pixel.

3.      Complete the blend() function to blend two images. For each pixel, you will add 60% (0.6) of the pixel from img1 to 40% (0.4) of the pixel from img2. Assume the two images are the same size.

    rotated 90 degrees; you'll have to create an empty image -
