[OpenLayers-Dev] animated zooming 1.0

[Duarte Carreira]

 Emanuel,

I think the animated zooming is great!

Here is my suggestion/whish list, if I may:

 - after zooming, the best effect would be to not hide the previous
tiles immediately, which shows a blank map while new tiles are loading.
Would it be possible to slowly replace them with the new ones as they
become available?
Maybe even turn the old tiles a bit transparent to show they are old?

Regards,
Duarte Carreira

> 
> You'll find my patch file in the ticket #442:
> http://trac.openlayers.org/ticket/442
> 
> Features in the current version:
> - zooming with the zoomslider -> scale all tiles by 
> shrinking/enlarging
> - scale all active/visible layers (what do you think about 
> the performance?)
> - simple zoomOut (gets a white frame)
> 
> Features for the next versions:
> - preloading specific tiles of lower zoomlevels to prevent 
> the white frame during zoomOut
> - scale the red rectangle in the overviewmap
> - animated zooming with +/- buttons like the demo [1] of 
> animatedPanning
> (#110)
> - animated zooming with mousewheel
> - animated zooming with +/- keys
> 
> Do you have more ideas/suggestions?
> Please test the demo and tell me what you think about it! Thanks.
