\subsection{Vector Graphics vs Raster Graphics}
-Raster Graphics: Stores the exact pixels as they would appear on a device. Causes obvious issues with scaling.
-Vector Graphics: Stores relative position of primitives - scales better. BUT still can't scale forever.
+Raster Graphics: Stores the exact pixels as they would appear on a device. Causes obvious issues with scaling. Lowest level representation of a document.

+Vector Graphics: Stores relative position of primitives - scales better. BUT still can't scale forever. Vector Graphics must be rasterised before being drawn on most display devices.
+
+Vector Graphics formats may contain more information than is shown on the display device; Raster Graphics always contain as much or less pixel information than is shown.

+Figure \ref{fox} shows an example of scaling. The top image is a vector graphics drawing which has been scaled. The bottom image was a raster image of the original drawing which has then been scaled by the same amount. Scaling in = interpolation/antialiasing/just scale the pixels depending on the viewer and scale; scaling out = blurring of pixels by averaging of neighbours. If you are viewing this document in a PDF viewer you can try it yourself! Otherwise, welcome to the 21st century.
