Well, this was a pain, because the real time smooth zooming and pamming integrated with the callout point transformation were too heavy. It would eat up to 40mb, which made the app freeze.
So, I removed the smooth zoom and pan and the callouts are repositioned only when you stop panning (i.e. you drop) the figure/map.
It’s a cool/ok app, I think. If I load a gif and place some 5 callouts, it will consume only 15/18 Mb of my memory. These are some tradebacks I had to make.
Of course you could try to implement those nice features. If you ever manage to do it, please let me know :0)
Please, be aware that I used Cairgorm.
Check out the app here (view source enabled).

Hi.
Was googling for a pan/zoom Flex component and saw your example with Callout integration.
Is this made upon the Adobe pan|Zoom component.??
Anyhows – love your solution, very nice indeed

Hi, Mark.
Im glad you enjoyed it :0)
Answering your quetiosn: yes, it was. Right now Im quite unhappy about this implementation, because it doesnt uses the Matrix approch for transformations…
The pan|zoom is modified as it receives any UIComponent and has that tinny navigator…
Not very scalable yet… It needs re-writing, which Ill be doing on vacations

Hi, Sri. Thank you for your comments.
I have done no improvements on this component. You will find, inside the projetc folder and inside the code, references of things I think should be improved (and suggestions). I dont really plan to work on it again, unless I need to use it on another project.
Doing it with Cairngorm was not a “correct” design choice, as it severely restrict its use, but thta was the framework I were using back then. Anyways, this decision can be justified, unless apealing to my lack of knowledge at that time.
You can find cairngorm.swc at Adobe Open Source: http://opensource.adobe.com/wiki/display/cairngorm/Cairngorm

Hi,
Thanks alot for the quick response. But there are several libraries available on this site: http://opensource.adobe.com/wiki/display/cairngorm/Cairngorm+Libraries. Could you please tell me the one which i need for using your code?? Is it Observer Library?
Please excuse me as i do not have knowledge about Cairngorm framework. I have seen your code. From what i understood is Cairngorm is used to structure the code in a MVC pattern. But theres nothing else done by Cairngorm Library for this pan/zoom functionality. Am i correct?
Thanks once again and Wish you a Very Happy New Year!

Ops, I gave you a link to C3. Go here, and download the binaries of c2.2: http://opensource.adobe.com/wiki/display/cairngorm/Downloads
And yes, it is used only to build the mvc classes.
Thanks and happy new year for you too
