C# Class SwfDotNet.IO.Tags.DefineMorphShapeTag

DefineMorphShapeTag defines a shape that will morph from one form into another.

Only the start and end shapes are defined. The Flash Player will perform the interpolation that transforms the shape at each staging in the morphing process.

Morphing can be applied to any shape, however there are a few restrictions:

  • The start and end shapes must have the same number of edges (StraightEdgeRecord and CurvedEdgeRecord objects).
  • The fill style (Solid, Bitmap or Gradient) must be the same in the start and end shape.
  • If a bitmap fill style is used then the same image must be used in the start and end shapes.
  • If a gradient fill style is used then the gradient must contain the same number of points in the start and end shape.
  • The start and end shape must contain the same set of ShapeStyle objects.

To perform the morphing of a shape the shape is placed in the display list using a PlaceObject2Tag object. The ratio attribute in the PlaceObject2Tag object defines the progress of the morphing process. The ratio ranges between 0.0 and 1.0 where 0 represents the start of the morphing process and 1.0, the end.

The edges may change their type when a shape is morphed. Straight edges can become curves and vice versa.

This tag was introduced in Flash 3.
