Runtime Versions: Flash Player 9, AIR 1.0

The Iris class reveals the movie clip object by using an animated mask of a square shape or a circle shape that zooms in or out. This effect requires the following parameters:
  • startPoint: An integer indicating a starting position; the range is 1 to 9: Top Left:1; Top Center:2, Top Right:3; Left Center:4; Center:5; Right Center:6; Bottom Left:7; Bottom Center:8, Bottom Right:9.
  • shape: A mask shape of either fl.transitions.Iris.SQUARE (a square) or fl.transitions.Iris.CIRCLE (a circle).

For example, the following code uses a circle-shaped animated mask transition for the movie clip instance img1_mc:

 import fl.transitions.*;
 import fl.transitions.easing.*;
 
 TransitionManager.start(img1_mc, {type:Iris, direction:Transition.IN, duration:2, easing:Strong.easeOut, startPoint:5, shape:Iris.CIRCLE});
