  1. Raster vs. Vector 2.02 Understand Digital Vector Graphics

  2. Purpose Raster Images – generally a better choice for photographs, the web, books, and magazines. Vector Images – generally a better choice for logos, illustrations, and large format designs, such a billboards.

  3. Scalability and Color • Vector graphics: • are resolution independent and do not degrade in quality when scaled (resized). • are not a good choice for photographs. • Raster graphics: • are resolution dependent and lose image quality when scaled. • can support millions colors, for photo realistic images.

  4. File Size and Portability • Vector graphics: • are small as they are represented by mathematical formulas. • Vector image formats are not as widely supported across programs. • Raster graphics: • can become very large based on image size and resolution. • Raster images have a variety of standard formats that are supported by most programs.

  5. Editable • Vector graphics are easily editable, as they are made up of anchor points, paths, and fills. • Raster graphics are more difficult to edit, but support a much broader range of effects. • Vector images can easily be converted to raster images but raster images are hard to convert to vector images.
