Week 6: CLEAR: Raster vs. Vector Graphics

A topic that was very clear to me this week was the difference between Raster and Vector graphics. 


There are 2 main types of multimedia images. The first is Raster images. Raster images are composed of pixels and are more commonly referred to as bitmap images. Raster images use a grid of individual pixels. Each pixel can be different shades and colors. Raster images need higher resolutions and for a smooth appearance must use the anti-aliasing function. Raster images are best used for photographs.


Vector graphics, on the other hand, use mathematical relationships between points and the paths connecting them to describe an image. Where Raster images are composed of pixels, Vector images are composed of paths. Since Vector graphics are mathematically formed they will appear smooth at any size. This is one of the main differences between Raster and Vector Graphics. 


Basically, you should use Raster graphics for photos with complex shading and use Vector graphics for all type, line art and illustrations.


Below is a basic showing a Vector versus a Raster graphic:
