Bitmap vs. Vector
Look at the below example to see the clear difference between a scaled bitmap logo and a scaled vector logo. We start with a 80×80 pixels logo and then scale it. The first example (bitmap) shows what this will look like if you take a GIF or JPG logo from one of the usual logo pages and resize it in Photosop. The second example (vector) shows how our logos work when loaded into Photoshop, where you enter the size it should have before loading.
