project 4 selection tools
Project 4 – selection tools
  • It is possible to make selections based on size, shape, and color
  • There are four basic sets of selection tools
    • Marquee
    • Lasso
    • Magic Wand
    • Pen
  • The best selection tool to use often depends on the characteristic of that particular area, such as shape and color
    • Geometric Selections – Marquee
    • Freehand Selections – Lasso
      • Lasso can trace a free-hand selection
      • Polygonal lasso sets anchor points in straight line segments
      • Magnetic lasso – combination; works best when a good contrast exists between the selection area and its surroundings
    • Color based selections – Magic Wand
project 4
Project 4

  • Moving a selection
    • Using the move tool, drag the tomato to the bottom left corner of the cutting board
    • Select  Deselect
    • Save (working)

    • Select the elliptical marquee tool
    • Try to select the olive bowl
      • It’s ok if your selection isn’t perfect
      • DO NOT release the mouse at this point
    • Still holding in the mouse, press the spacebar to re-position your selection
    • Release the spacebar, but not the mouse, to continue with your select
    • Repeat this process (without ever letting go of the mouse) until your selection is precise
  • Move the olives to the bottom right corner of the cutting board
project 43
Project 4
  • Selecting from a center point
    • Select the elliptical marquee tool

    • The graphic is now effectively a color negative of itself
project 44
Project 4
  • Moving and Duplicating Simultaneously
    • With the move tool selected, hold down Alt
    • Continue holding down Alt and drag a duplicate of the graphic so that it is near the upper right corner of the cutting board
