The images $($a$)$ and $($b$)$ below $($from YouTube user brusspup$)$

demonstrate a line moir$$ animation effect. When image $($b$)$ is

printed onto a transparency, and translated horizontally over

image $($a$)$ then the viewer perceives a six$-$frame animation.

Image $($c$)$ shows a magnified part of image $($b$)$ to illustrate that

it is a mask image that alternates between a thin transparent

band followed by a thicker opaque band.

Image $($d$)$ contains a single frame of an animation sequence.

Write a program using Python$-$inspired pseudo$-$code to create

five additional animation frames and combine them into a six$-$

frame line moir$$ animation image of the object rotating

counter$-$clockwise and moving horizontally from right to left.

You can assume that image $($d$)$ is provided in a file called

frame$0.$ png in your current working directory. You are not

given the mask image and must generate that using the

dimensions of image $($d$).$ For full marks, your pseudo$-$code

must write an image file to disk called linemoire.png that

contains the line moire animation image to be printed onto

ordinary paper and you must write an image file called

mask.png that contains the mask that must be printed onto a

transparency to reveal the animation.
