Most pictures that you simply see on a pc are made of pixels, little rectangles that ar totally different colours. If you look very close at your image you'll see them.
The Fab Lab machines do not know a way to cut pixels.
We have to convert our image into lines and shapes that the machines will perceive. we have a tendency to decision this sort of file a vector file.
Another good thing about turning our file into vectors is that you simply will size the image as massive as you would like and it will not get bleary or loose resolution.
