I need Script for zooming and panning images in a smoother way. - Flash

In a smoother way? It is pretty much smooth. What version of flash are you using?

There are 3rd party tweener libraries you can use. That might be worth looking at.

Image should be zoom and able to pan within the specified area. I mean I placed controls for that like zoom in, out, pan up left right down etc. also need without these controls. I am using Flash cs3 with as2.0 even its ok with as3.0

What Frame Rate are you using? Is it between 24-36 FPS?

Whatever fps within 26 to 30. I need a sample fla or effective tutorial on that with full controls.
