Assignment

First observe how Andy Warhol took a picture of Marilyn Monroe and turned it into a work of art:

You are going to apply similar transformations to this picture of a famous local person:

The picture of President Cathy McCartney is exactly one quarter the size of the full image. The size of her picture is one half the width of the full image, and the height of the picture one half the full height.
The file is coded as a jpg file.

You need to write a JES program that contains several functions, one function for each basic transformation.
Your program will copy the image of the president in the 3 other quadrants, erasing in the process the orange background and the smiley faces. We'll refer to these as quadrant images.
The final image will contain four copies of the president's head. All four heads will be oriented correctly. In other words, none of the heads will be upside down.
Your program will make one of the quadrant images black and white.
Your program will transform one of the quadrant images of the president and divide it into 4 quarters, applying an image transformation to the top-left and bottom-right corners of this image, as illustrated with this picture of the cat below. The type of color transformation you use is up to you. But it should be visible.

The last quadrant image will be a color transformation that will divide the quadrant image into stripes, as illustrated on the cat image below. The type of color transformation you use is up to you. The number of horizontal stripes, and their width are up to you. The type of color transform is also up to you, but cannot be the same as the transformation used for the image divided into quarters.
