Simple program to take an image and pixelate it.

It works by taking the average colour around an area, and then filling that area with that colour

Requires SFML library

On Ubuntu:

sudo apt-get install libsfml-dev

Building:

git clone https://github.com/Hopson97/Pixelator.git
cd Pixelator
cmake .
make

./pixelator <image-file> <pixel-size>

The pixel size must be a number divisible exactly by both the image width and height

./pixelator monalisa.jpg 12

Output:
