New issue 246 by chittu.sahoo: setMaxScale and setMinScale not working.
http://code.google.com/p/piccolo2d/issues/detail?id=246
Hi Team,
I am first time user, so I tried to achieve with my limited knowledge.
Basically facing 2 issues:
1. restricting Max and Min size of zooming does not work with
PMouseWheelZoomEventHandler
2. Canvas look is shrinking for repeated Zoom IN/OUT using mouse wheel,
(like zoom in one step then zoom out one step, repeat...)
What steps will reproduce the problem?
1. Used the MouseWheelZoomExample and added
mouseWheelZoomEventHandler.setMinScale(1.0d);
// install mouse wheel zoom event handler
final PMouseWheelZoomEventHandler mouseWheelZoomEventHandler = new
PMouseWheelZoomEventHandler();
getCanvas().addInputEventListener(mouseWheelZoomEventHandler);
mouseWheelZoomEventHandler.setMinScale(1.0d);
I tried with various values for both Max and Min, but don't see any
restriction while zooming.

What is the expected output? What do you see instead?
It should restrict upon reaching max and Min value
What version of the product are you using? On what operating system?
1.3.1 Ubuntu 12.4
Please provide any additional information below.
I was trying to set the max and min zoom scale, so need to override the
mouseWheelRotated() function, which is not completely achievable, then I
encounter another issue,Zoom-in and Zoom-Out by one step continuously
shrinking the look and also there is center coordination shift. so in other
word, we can't get back to original size once mouse wheel zooming option.
