OpenStreetMap
Hi all
I made a new Slippy Map.
The new thing is, that it's possible to zoom in an out very fast.
At least at my computer it works excellent.
Turn your mouse wheel at:

On my 1 GHz Celeron Laptop it zooms with about 15 frames/second.
I tested it with Firefox 2.0, Internet Explorer 6.0 (Linus/Wine - strange error with missing tiles), Opera, Konqueror (no wheel mouse support) Ubuntu Linux.
Keycodes, mouse scrollspeed, ... are maybe different on different system - it's a beta version.
Feedback is welcome.

Yes, that's very impressive.
You might consider to give a fast scroll, maybe, also & , if you want even more work to do :)
Well done!

Yes, zooms very nicely. I think though it should snap to the zoom levels as they are rendered -- the maps don't look good if they aren't shown pixel-to-pixel.

Fast scroll works very well on my computer.
There is an extra speed boost if you turn the mouse wheel very fast.
On my computer I have a mouse wheel area on my touchpad and that can be very different to real mouse wheel.
If you hold the ALT-Key it zooms 10 times faster now if you turn the wheel.

snap to zoom:
Snap:
If you use doubleclick it snaps to a good looking zoom levels.
I know, that's a problem - but how to solve it? It's not a question of how to do the javascript code, it's a usability question.

Hey, it really looks great. But on the other hand it lacks my favourite feature of the current openlayers slippy map, which is the "hold Shift and drag a rectangle with mouse button pressed around the area you wish to zoom into". Maybe that could be added?

Works nice on my MacMini, except that the mouse scroll wheel doesn't work

Very nice!
I agree about the scroll-zoom being too slow. With ALT it is perfect for me.
Also I agree that snapping to the zoomlevels would be great. The soft zoom is a sweet effect (always missed it).
(I never knew about the Shift-Drag zoom selection for the normal slippy map, that is awesome.)
When holding Shift on yours I get rectangles being drawn and no way to stop them. :)

Can you force the browsers to use bilinear scaling instead of the default nearest neighbour?
