Most of those zoomers use preprocessed images. I.e. there are large and small versions already on the server. A more extreme example is Zoomer which during setup you run an app that cuts your image into bunches of squares and then during runtime web client load squares as needed.
I would start with just large and small versions, use a mask on the large, figure out the ratio between the large and the small and position the large image in reverse proportion to the dragged hourglass frame times the ratio. -jonathan On Fri, Sep 4, 2009 at 9:43 AM, thomas horner<tho...@megawattmedia.co.uk> wrote: > thanks i figured this out in the end my self. > > you dont happen to know anything about building a java style zoom viewer in > as3; > > http://www.magictoolbox.com/magiczoom/ > > i assume you need to use bitmapdata > > > > -----Original Message----- > From: flashcoders-boun...@chattyfig.figleaf.com > [mailto:flashcoders-boun...@chattyfig.figleaf.com] On Behalf Of jonathan > howe > Sent: 04 September 2009 14:34 > To: Flash Coders List > Subject: Re: [Flashcoders] problem with dictonary on dynamic buttons > > Your dictionary is built off of that goto attribute but then you're > passing in an instance of the object into the dictionary array. > > You have not assigned a name property to your assets.
