Vector and Bitmapped graphics

-Vector graphics: Image represent and stored as a collection of shapes, together with data (parameters) defining how the shapes will be produced and where they will be located
-Bitmapped images: Image represented and stored as a collection of pixels which displayed make up the image
-Rendering: Close the shape and apply the colours in
-Vector graphics enable images to be composed of filled shapes
-Each object can be manipulated individually
-Scaling objects is easy
-Anti-aliasing allows you to correct the pixellation effect
-Rasterising converts vector to bitmap. Tracing is opposite
-Examples of bitmapped images: GIF, JPEG, TIFF, BMP, DIB, PCD, PNG, etc
