Acceleration Controls

Acceleration refers to distortion of the text in the horizontal direction. This is useful for 3 dimensional or other special effects. The buttons are control buttons and it is possible to further edit the acceleration in the Acceleration widget to have fine-grained custom control.

Reform Text Acceleration Controls

1. Linear acceleration button

The default. No acceleration or uniform acceleration.

2. Ease in acceleration

Text starts very stretched, then becomes very compressed.

3. Ease out acceleration

Text starts very stretched, then becomes very stretched. 

4. Shallow sigmoid acceleration

Text starts very compressed, becomes very stretched, then ends very compressed. This one is set up to represent text printed on cylindrical object such as a can or a bottle.

5. Steep sigmoid acceleration [A misnomer]

Text is uniform, but here are two handles which you can use in the acceleration widget control to define your own sigmoid acceleration profile easily.

6. The acceleration widget

This displays the acceleration graphically, and allows for fine control or custom accelerations.

7. Acceleration widget control handles

With a linear acceleration you get no handles (no editing possible), with ease in or ease out one handle, and with the sigmoid controls, two handles. Grab and pull the handles, and the acceleration adjusts to reflect the new handle position. Note that sometimes the handles will appear to get stuck. This is to prevent the entering of extreme accelerations which would produce undesirable results.
