Vector vs. Pixel

  • There are two main types of applications that you will use to create and edit pictures and graphics:
    Pixel – “raster” programs like PhotoShop that allow you to edit pictures using a series of pixels
    Vector – “object” programs li Illustrator that allow you to create and edit object using a series of lines and fills
  • Drawings created in vector programs like illustrator are composed of separate, distinct and mathematically defined objects that can be edited and resized without compromising resolution
  • Vector objects have smooth sharp edges regardless of the size that they are displayed – the resolution will depend on the output media like a printer or the screen
  • In Illustrator, the key building blocks that you will be using are the Bézier object – composed of anchor points connected by curved or straight lines that may or may not be filled:Where you can see that the second “E” is highlighted – showing the anchor points, lines and fillCreating Files
