Bitmap vs. Vector Graphics

Vector? Bitmap? What’s that?

In a nutshell, bitmap images are a bunch of dots. If you blow up the image, the dots get bigger and the image looks pixelated. (horrible)

Vector images are curves (or angles). If you blow up the image, the curves get bigger, but no matter how big you blow it up, it will be an exact replica of the original.

But if the file was in a vector format, you can blow it up as big as you want and it doesn’t get blurry.¬†(click on image to blow up)
