  1. 1. Raster vs. Vector
  2. 2. Raster a.k.a. bitmaps• Raster images use a rectangular grid of picture elements –pixels – to represent images. Each pixel is assigned a specific location and color value.• Bitmaps are the most common electronic medium.• Used for photos and drawings that represent subtle gradations in color.
  3. 3. Raster (con’t)• Raster images are resolution dependent which means they contain a fixed number of pixels. As a result they can lose detail and become jagged or pixelated as when magnified.• Can Require large amounts of storage space
  4. 4. Vector Images• a mathematical means of representing pictures by drawing lines and shapes in relationship to designated coordinates. The saved file contains instructions for drawing the image, which can be enlarged or reduced without losing quality.
  5. 5. Vector• Vector graphics are resolution independent. They can scaled and resized without losing clarity.• Best choice for artwork such as logos that are used in various sizes and many different medias.• Flash uses Vector Art which is the standard for web animations.
  6. 6. Comparison of Raster and Vector
  7. 7. Raster Vector Together• Flash is Vector Art• Photoshop is primarily Raster Art• Flash will support both graphic types – you can import raster images but not edit them.
