A shape tween is one of the easier methods to morph an object in Flash. With Flash's shape tween, you create two different shapes, such as a circle and a square, and place them on two different frames (time points) on Flash's timeline. You then activate Flash's shape tween to establish the first shape as the shape to be morphed and the second shape as the shape to be morphed into. When you play the morphing animation, Flash will interpolate the shape for each frame between the original shape's frame and the target shape's frame such that the shape will smoothly transform itself into the target shape.
Flash's Copy Motion feature can be used to convert the shape tweens you have created with Flash's shape tween tools into Flash-readable ActionScript code. This allows you to apply shape tweens you created in Flash authoring mode to different shapes with different motion paths in different animations (with very little coding). In order to convert the shape tween to code, you have to create a motion tween and apply the shape tween in the motion tween. The "Copy as Motion to ActionScript 3" option is used to create the motion file and save a copy of the code in Flash's clipboard. This option appears in the context menu when you right-click your mouse within the motion tween on the Flash timeline.
Text morphing is the process of transforming a letter or number into another letter, number or different shape all together. Shape hints can be used to control the actual morphing transformation of the letters between individual frames to set constraints on how the shape morphs. Different frames between the beginning point and end point of the animation are selected to add the shape hints. Morphing text in text boxes requires that you first break apart the text with the Flash's Break Apart authoring tool (located in the Modify menu).
Bit maps such as JPEG images produced with Adobe Photoshop and digital cameras must be modified before you can apply a shape tween to them, After the bitmap image is placed on the stage, the image must be selected and traced with Flash's Trace Bitmap tool (located in the Bitmap menu within the Modify menu).
