For your final image manipulation problem in this worksheet, write a program that takes an image in any mode and increase its size as described on the previous slide.

The program should ask the user to enter a filename, an integer multiplier for the width and an integer multiplier for the height. It should open this file, perform the transformation and then save the larger version of the image to the file 'output.png'.

Here is an example of the effect your program should produce:

Enter a filename: astronaut.png Enter a width multiplier: 1 Enter a height multiplier: 2
