- Two major types of graphics
- Bitmap (or raster)
- most common for photorealistic images
- describe images pixel by pixel (or as a collection of dots)
- are resolution dependent, thus scaling upward leads to loss of quality
- Vector
- more common for line art such as logos or clip art
- describe images mathematically as collections of lines (straight and curved, such as circles)
- are resolution independent, thus can be scaled infinitely
