Tween: Short for in-betweening, the process of generating intermediate frames between two images to give the appearance that the first image evolves smoothly into the second image. iSlide add-in calculates and defines how the objects should move and change during the tweening process.
The initial interface of "Tween"
Set the number of intermediate frames
Add animations: If checked, it will automatically generate animation after tween
Length per frame: Unit duration of each frame
More details of the tween parameter settings
Example ONE: The bouncing cylinder
Insert shape > Circle > Format > Shape Effects > 3-D Options, set the top bevel (Height: 300 pt.)
Copy this circle and perform 3-D Rotation and set perspective value
Set the parameters of Tween Animation
You need the check and set the [Duration]
Align the shapes by using the alignment tool, then start the slide show to see the cool effect
Select the shapes need to be aligned
Click Format > Align, then choose [Align Center] and [Align Middle] respectively, the shapes will overlap completely
【Shape + Color】: Set Tween Animation
【Note】To use [Tween Animation] to achieve variant animations, you need to use the shape with handle in PowerPoint’s shape options
【Shape + Color + Transparency】: Set Tween Animation
Example TWO: Picture Gradient Mask
Please check the following gif for specific operation. We don’t need to add animation in this example, so don’t check [Duration] when setting the Tween Animation parameters.
