The Default Envelope permits
the user to distort the contents of the envelope in a free form manner. All sides are treated as curves. The other Preset Envelope apply a specific shape to the contents as indicated by the icons. Clicking on any corner produces
Bezier control handles, which when dragged change the shape of the envelope and its contents in real time. The Default Perspective Envelope treats all sides as straight lines and permits each corner to be manipulated
separately. We will be working with the Default Perspective envelope. |
